The resulting value is assigned to a long variable. It is counter productive in terms of time to read text books more than (around) 250 pages during MSc program, Adding GPL classpath exception to program. What is the difference between #include and #include “filename”? Similarities Between int and long Java provides a number of numeric data types while int and long are among those. unsigned int 0～4294967295 int 2147483648～2147483647 unsigned long 0～4294967295long 2147483648～214748 int ,long , long long类型的范围 - kuangbin - 博客园 首页 Java Convert long to int. This article discussed the difference between two data types that are int and long. long int long int即long，给人的感觉好像是长整型，但实际上，它和int一样，只有32位。cppreference给出的定义是——int - basic integer type. The keyword ‘int’ is used to declare an integer. The specifier is how you tell the compiler what the type is but you can use different specifiers to end up at the same type. Although the C++ standard itself doesn't specify the minimum ranges of integral types, it does cite C99, in 1.2 Normative references, as applying. As for the actual sizes used.. depending on which standard you read, each size may have a minimum number of bits, but they're all defined such that each is, Long taking 4 bytes is only valid on Win64, it's platform dependent. So, if your program is supposed to store small numbers then use an int type. Even with the innocuous looking C4244 warnings it's not easy to detect. There's a good summary of 64-bit data models here. Both int and long are predefined data types supported by programming languages such as Java. long (unsigned long) long (unsigned long) long long (unsigned long long) long long (unsigned long long) 이름이 두 개의 밑줄(__)로 시작하는 경우 데이터 형식은 비표준입니다. On Windows, the representation of "long double" may be increased to 10 bytes by use of the command line switch /Qlong-double. Java provides a number of numeric data types while int and long are among those. 1.Point, Tutorials. Basic types Main types. Hence long on its own is neither a type nor a modifier as your question posits, it's simply a specifier for the long int type. long long int ±9223372036854775807; これなら入る。で、それを使って書い … Does something count as "dealing damage" if its damage is reduced to zero? The maximum value that can be stored in unsigned long long int is stored as a constant in header file whose value can be used as ULLONG_MAX. Summary. char ( 8 bits) : -128~127 (%c) unsigned char (8 bits)：0~255 Therefore, it cannot be used as an identifier such as a variable name or a method name. So, if your program is supposed to store small numbers then use an int type. When Long.intValue() is used to get an integer from a Long, no exception is thrown if integer overflow occurs. Make 38 using the least possible digits 8. Those memory locations are called variables. The range of values is from -128 to 127. uchar #. The Microsoft C++ 32-bit and 64-bit compilers recognize the types in the table later in this article. Does authentic Italian tiramisu contain large amounts of espresso? 6. If you specifically need 64 bits, use the types defined in stdint.h and the format macros in inttypes.h. In programming languages such as Java, the programmer should specify the data type. Many platforms / ABIs use the LP64 model - where long (and pointers) are 64 bits wide. 下表中指定的範圍是兩端皆包含。 The unsigned long value is the argument plus 2 64 if the argument is negative; otherwise, it is equal to the argument. The size of the "int" integer type is 4 bytes and the size of the "long long" integer type is 8 bytes for all the above combinations of operating system and architecture. The long is a larger data type than int. The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long.The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. Why do Bramha sutras say that Shudras cannot listen to Vedas? This article shows how to write a Java program to convert integer or int to the long data type. short (unsigned short). int型って使ってますか？ 整数を扱う場合に使いますよね。整数を扱うデータ型にはよく使うint型の他にもlong int型、short int<型があります。扱う値の範囲でこれらの型を使い分けま Using long long with win32 listboxes and the like is wont to play havoc with your memory and other variables- even if the limits aren't breached. long long and long long int are at least 64 bits. Typecasting in java is performed through typecast operator (datatype).. See the following C program for the usage of the various data types… The int and long are primitive data types; the int takes 32 bits or four bytes of memory while long takes 64 bits or 8 bytes.. int example long example. The controlling parts of the standard (C++11, but this has been around for a long time) are, for one, 3.9.1 Fundamental types, section 2 (a later section gives similar rules for the unsigned integral types): There are five standard signed integer types : signed char, short int, int, long int, and long long int. The range of values is from -128 to 127. uchar. Long variables are extended size variables for number storage, and store 32 bits (4 bytes), from -2,147,483,648 to 2,147,483,647. It has a range of −9,223,372,036,854,775,807 to +9,223,372,036,854,775,807.If you only deal with positive numbers then unsigned long long can be used which has a range of 0 to 18,446,744,073,709,551,615.. long long i; unsigned long long j; scanf ("%lld %llu",&i,&j); //Format specifier for long long int can also be %lli In programming, it is required to store data. Trajectory plot on phase plane for a desired initial conditions, Why do I have clipping in this emitter follower, Pearson correlation with data sets that have values on different scales. The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long.The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. unsigned long long int : 8 : 0 to 18,446,744,073,709,551,615 %llu : signed char : 1 -128 to 127 %c : unsigned char : 1 : 0 to 255 %c : float : 4 %f : double : 8 %lf : long double : 16 %Lf : We can use the sizeof() operator to check the size of a variable. As for the range requirements, the C++11 standard references the C11 standard, which has actual ranges. Lithmee Mandula is a BEng (Hons) graduate in Computer Systems Engineering. your coworkers to find and share information. So the authors/steering committee have decided that if long int (which is 8 bytes long) is insufficient then you should be using the gmp (gnu multiple precision library). @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } It is the process of converting a one data type to another data type. The type of an integer literal is determined by its suffix as follows: If the literal has no suffix, its type is the first of the following types in which its value can be represented: int , uint , long , ulong . The variable b is an int and has the value 20. The equals operator implicitly converts the integer to long. If there is no typecasting, it means the integer value is assigned to the byte variable so there will be a compile-time error. msdn.microsoft.com/en-us/library/s3f49ktz.aspx, Podcast 296: Adventures in Javascriptlandia. Look them up on Wikipedia for details. The uchar integer type also occupies 1 byte of memory, as well as the char type, but unlike it uchar is intended only for positive values. It has a range of −9,223,372,036,854,775,807 to +9,223,372,036,854,775,807.If you only deal with positive numbers then unsigned long long can be used which has a range of 0 to 18,446,744,073,709,551,615.. long long i; unsigned long long j; scanf ("%lld %llu",&i,&j); //Format specifier for long long int can also be %lli If I convert it to an 'unsigned long long', and printf("%llu ", num) -- , I at least get a POSITIVE number, but it is still not the correct number. long is a modifier, you can use it with double also as long double. It is also known as implicit type casting or type promotion. This is implemented with printf() function for printing the long integer value stored in the variable. 1 - Está sendo irrelevante pra mim aqui colocar long int, unsigned int ou unsigned long int, o compilador está alocando 4 bytes de memória apenas, números negativos e positivos. In this program, the sizeof operator is used to find the size of int, long, long long, double and long double variables.. As you can see, the size of long int and long double variables are larger than int and double variables, respectively.. By the way, the sizeof operator returns size_t (unsigned integral type).. Many platforms / ABIs use the LP64 model - where long (and pointers) are 64 bits wide. Asking for help, clarification, or responding to other answers. This function operates like atol to interpret the string, but produces numbers of type long long int (see atol for details on the interpretation process). long is equivalent to long int, just as short is equivalent to short int. Making statements based on opinion; back them up with references or personal experience. We can convert int to long in java using assignment operator. Parses the C-string str interpreting its content as an integral number, which is returned as a value of type long long int. Think about the data and what possible values it can have, and use the best-fitting type. Keep in mind though, that a long long is not necessarily 64 bits. In this example, we are declaring two variables a and b, a is unsigned int type and b is unsigned long long int type. 6 comments. Basic types Main types. The long data type is a 64-bit signed two’s complement integer. This value is converted to a string of ASCII digits in hexadecimal (base 16) with no extra leading 0s.. Java long to int example. Typecasting can be performed on data types. The int and long are primitive data types; the int takes 32 bits or four bytes of memory while long takes 64 bits or 8 bytes.. int example long example. According to the above program, the variable a is an int and has the value 10. C++において、int型とlong型とlong long型の違いについて教えていただきたいです。 特に表現できる上限値について知りたくて、調べてみると下記な認識です。 int -> 2^31 - 1 long -> 2^31 - 1 long long -> 2^63 - 1 intとlong longの違いはわかるのですが、longの位置付けがよくわからないです。 Why is unappetizing food brought along to space?

The int data type is used to store numeric values without decimal points. Silly, no? We can convert long to int in java using typecasting. This looks confusing because you are taking long as a datatype itself. 你懂int类型吧，int 在内 copy 存占两个字节 ，范 2113 围是 5261-32768 ~ 32767 而long long在内 4102 存占八个字 节， 范围 是-922337203685775808~922337203685775807 long long int不是 1653 所有编译器都支持的，有些支持这种数据类型的，可能是真支持，也可能是模拟支持，总之它不是标准类型。 What is the difference between const int*, const int * const, and int const *? There is nothing to do extra because lower type can be converted to higher type implicitly. Alex Louden # 07 Sep 2010. One byte is equivalent to 8 bits. The license length should be actually 20 characters( a valid license in my case will always be 20 characters), so for convenience, I append 00 to the license and input. Each variable has a specific type of data to be stored. The maximum possible integer input can be taken in C using long long int. This function operates like atol to interpret the string, but produces numbers of type long long int (see atol for details on the interpretation process). In this program, the sizeof operator is used to find the size of int, long, long long, double and long double variables.. As you can see, the size of long int and long double variables are larger than int and double variables, respectively.. By the way, the sizeof operator returns size_t (unsigned integral type).. Available here, Filed Under: Programming Tagged With: Compare int and long, int, int and long Differences, int and long Similarities, int Bytes, int Definition, int Keywords, int Max Value, int Min Value, int vs long, long, long Bytes, long Definition, long Keywords, long Max Value, long Min Value. Difference between Short, long and Long long int in C programming? The char type takes 1 byte of memory (8 bits) and allows expressing in the binary notation 2^8=256 values. In C prior to C99 (but not in C++), unsuffixed decimal values that do not fit in long int are allowed to have the type unsigned long int. A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. While in Java a long is always 64 bits, in C++ this depends on computer architecture and operating system. In above program, the num1 variable has value 10. To learn more, see our tips on writing great answers. 어떤 문제는 long long 자료형을 써야할 때가 있고 (int 형의 범위를 초과해서), 어쩔때는 이러한 long long 을 scanf 나 printf 로 출력해야 할 때도 있겠죠 (저 같은 경우에는 int 나 float 같은 것 만 대충 알고 있었습니다). Java int to long Example. The long data type is a 64-bit signed two’s complement integer. It will iterate 5 times. What political advantages (if any) a kingdom can have when power is passed on to the heir as early as possible? The char type can contain both positive and negative values. Each memory location can store a specific type of data. The float and double data types are used to store numerical values with decimal points. What is the difference between “long”, “long long”, “long int”, and “long long int” in C++? As int is a larger data type than a byte, it is necessary to typecast into byte in order to store into a byte variable. Hi, I have an integer value of 18 characters, which i declare as a long long int, say long long int license. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. Why do C fundamental types have identifiers with multiple keywords. When the ‘i’ value becomes 6, the condition becomes false and get out of the loop. You can create a new name for an existing type using typedef. Char, Short, Int and Long Types char. If doing math with integers at least one of the values must be of type long, either an integer constant followed by an L or a variable of type long, forcing it to be a long. Here, we are going to learn how to convert long primitive type into int and Long object into int. The int and long are two data types. The "int" part simply differentiates between an integer type and floating point, character, or other non-integer type. long doubles are a bit odd. Let's see the simple code to convert int to long … For example, a long is 64 bits on Linux and 32 bits on Windows (this was done to keep backwards-compatability, allowing 32-bit programs to compile on 64-bit Windows without any changes). Use this datatype when you need a number to have a greater magnitude than can be stored within an int. Igor Skochinsky # 09 Jan 2010. Maybe in the future you should expect compilers to translateintto be 64 bit. The size_t data type is used to represent the size of an object. 2.“Type conversion in Java with Examples.” GeeksforGeeks, 5 Jan. 2017. ConvertDataTypes.com Convert data types programming in one click ! @user2612743 - to be safe, think about what your requirements are and use the appropriate type. Parses the C-string str interpreting its content as an integral number, which is returned as a value of type long long int. The format for "long long" is %lld (or %llx etc.). Any help would be appreciated. The maximum possible integer input can be taken in C using long long int. what is format for sprintf to convert long long integer (64 bits) to string? It is considered good C++ style to avoid short int long ... and instead use: These (int*_t) can be used after including the header. If I convert it to an 'unsigned long long', and printf("%llu ", num) -- , I at least get a POSITIVE number, but it is still not the correct number. Besides the minimal bit counts, the C++ Standard guarantees that 1 == sizeof (char) <= sizeof (short) <= sizeof (int) <= sizeof (long) <= sizeof (long long).. Stack Overflow for Teams is a private, secure spot for you and 주로 int와 long long을 구분하며 사용하실 땐, 주어지는 입력값의 범위를 고려해보시고 그 값이 int로 표현이 불가능한 값이면 long long, long long으로도 불가능하면 BigInteger를 건들면 크게 문제를 해결하는데 애로사항은 없으실 겁니다. The data is stored in memory. In programming, it is necessary to store data. All rights reserved. A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. What are the differences between a pointer variable and a reference variable in C++? We can read and print unsigned long long int type values using "%llu" - here l for long and u for unsigned. In C, it is denoted by long. This article discussed the difference between two data types that are int and long. Hence the minimal ranges as set out in C99 5.2.4.2.1 Sizes of integer types are applicable. The widening happens in a byte, short, int, long, float, double. 2. If its name begins with two underscores (__), a data type is non-standard. 출처는 MSDN입니다. There's also a table 9 in 7.1.6.2 Simple type specifiers, which shows the "mappings" of the specifiers to actual types (showing that the int is optional), a section of which is shown below: Note the distinction there between the specifier and the type. Type Name Bytes Other Names Range of Values int 4 signed –2,147,483,648 to 2,147,483,647 unsigned int 4 … size_t is in . In the for loop, ‘i’ is the counter variable. 1.将long型转化为int型，这里的long型是基础类型： long a = 10; int b = (int)a; 2.将Long型转换为int 型的，这里的Long型是包装类型： Long a = 10; int b=a.intValue(); 3.将Long型转换为 _来自java，w3cschool编 … When assigning a long value to int, it is required to typecast. Any help would be appreciated. In both cases, the int is optional. long Type Modifier. The long is the largest data type. Overview and Key Difference A data type int is a most commonly used data type that holds an integer value in it. Since long is larger data type than int, we need to explicitly perform type casting for the conversion. A Computer Science portal for geeks. In C programming we need lots of format specifier to work with various data types. A long integer is a data type in computer science whose range is greater (sometimes even double) than that of the standard data type integer. What if developers don't want to spend their time on manual testing? Other data types are smaller than long. It is 64 bits in width. long long 형식의 변수는 %u %lld , %lli , %llo , %llu , %llx를 이용하여 출력을하면 제대로 된 값을 얻을 수 있다. The int data type is a 32-bit signed two’s complement integer. Is it legal to put someone’s mail in their mailbox? What is the difference between type “long” in C++/CLI and C#? Java Convert long to int. Does software exist to automatically validate an argument? Thanks for contributing an answer to Stack Overflow! She is currently pursuing a Master’s Degree in Computer Science. Note: this allows the extreme case in which bytes are sized 64 bits, all types (including char) are 64 bits wide, and sizeof returns 1 for every type. To convert higher data type into lower, we need to perform typecasting. This also helps the compiler make additional optimizations without breaking the original code intent, such as if it has to load additional libraries to handle numbers larger than the natural bit-width of the target platform. In Java, the data range is from -9,223,372,036,854,775,808(-2^63) to 9,223,372,036,854,775,807 (inclusive) (2^63-1). As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long. Ditto for long long being a specifier for the long long int type. How to fix runtime error on sieve, the runtime error is signed integer overflow: 46349*46349? rev 2020.12.18.38240, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide. To declare an integer variable, the keyword ‘int’ is used. short int ±32767; int ±32767; long int ±+2147483647; あれ、longでも足りない…と思ったらC99にはlong long intという物があって. When did the IBM 650 have a "Table lookup on Equal" instruction? Long Int Format Specifier %ld. The int and long data types in Java. long long int : 8 -(2^63) to (2^63)-1 %lld : unsigned long long int : 8 : 0 to … When assigning a smaller data type to a larger data type, there is no casting required. Likewise, each data type can store a particular value depending on the type. In a certain sense, int is a more abstract data type thanchar,short,longorlong long, as you cannot be sure about the bitwidth. We can use the Java assignment operator (=) to convert lower data type (integer) to higher data type (long). long (unsigned long) long (unsigned long) long long (unsigned long long) long long (unsigned long long) 如果其名稱開頭為兩個底線 (__)，則資料類型是非標準的。 If its name begins with two underscores (__), a data type is non-standard. long is nothing but just the shorthand for long int when you are using it alone. [] Floating point typefloat - single precision floating point type. The int and long data types in Java. The long data type is a 64-bit signed two’s complement integer. Note that int and long are the same size and if you want a 64 bit integer then you need to use long long (or unsigned long long). A long integer can represent a whole integer whose range is greater than or equal to that of a standard integer on the same machine. The size_t data type is used to represent the size of an object. long int即long，给人的感觉好像是长整型，但实际上，它和int一样，只有32位。cppreference给出的定义是—— 在实际的使用中，long与int几乎没有区别，比如—— 既然long int与int相同，那么为什么还有long int这种尴尬的类型呢？ 原因是早期的C编译器定义了long int占用4个字节，int占用2个字节，long int是名副其实的长整型。在ANSI C的标准中，对长整型的定义也是long int应该至少和int一样长，而不是long int 一定要比int占用存储字节长。所以，正确的关系应该是—— long≥int≥shortlong≥int≥shortlong\geq int\… There are data types such as int, char, double and float etc. Her areas of interests in writing and research include programming, data science, and computer systems. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. This doesn't necessarily mean that a long long is wider than a long. Maximum value for an object of type unsigned long long int 18446744073709551615 ( 2 64 -1 ) or greater* * the actual value depends on the particular system and library implementation, but shall reflect the limits of these types in the target platform. It is an integer. long double doesn't guarantee much other than it will be at least as wide as a double. There are data types such as int, char, double and float etc. The long is a predefined data type provided by languages such as Java. The size of a long long is 8 bytes (as it should be), so I am fairly certain that the problem lies in my usage of printf(). In programming languages such as python, it is not necessary to declare the variable type. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Yes obviously...not only long...int takes 4 bytes and 2 bytes depend on the platform, no doubt. 以 int 為例，16 位元電腦 int 佔 16 bits；32 位元電腦 佔 32bits； 但可以確定的是： short int <= int <= long int 至於詳細情形，仍需依使用者環境所定，下述為 32 位元電腦之情形。 1. If its name begins with two underscores (__), a data type is non-standard. Those data are stored in memory locations. Typecasting in java is performed through typecast operator (datatype).. In many cases, this can be inferred by the compiler, so it can be dropped--This is why "unsigned" is the same as "unsigned int", for example. ④int的长度没有确定的规范，这和机器的字有关系，一般微机字长位16位或32位，如果使用的机器字长位32位，那么程序中int就表示32位长，那么64位字长机器上是否意味着int表示64位长呢？这个需要大神回复。 As nouns the difference between integer and long is that integer is (arithmetic) an element of the infinite and numerable set {,-3,-2,-1,0,1,2,3,} while long is (linguistics) a long vowel. It is also an integer. So are long long and long long int. The %ld format specifier is implemented for representing long integer values. Parameters str C-string containing the representation of an integral number. Format specifiers defines the type of data to be printed on standard output. Returns a string representation of the long argument as an unsigned integer in base 16.. The "int" part is simply assumed unless the programmer specifies something else, such as "char" or "double". The char type can contain both positive and negative values. “Java Basic Datatypes.”  Tutorials Point, 8 Jan. 2018.Available here 5. A maximum integer value that can be stored in an unsigned long long int data type is 18, 446, 744, 073, 709, 551, 615, around 2 64 – 1(but is compiler dependent). The difference between int and long is that int is 32 bits in width while long is 64 bits in width. Size of char : 1 Size of int : 4 Size of short int : 2 Size of long int : 4 Size of float : 4 Size of double : 8 Size of wchar_t : 4 typedef Declarations. Char, Short, Int and Long Types char #. That last part, using a "long" to get 32-bits when int is 64-bits, is incorrect. The char data type is used to store a single character value. Since this is a prerequisite to compile gcc/g++ (well, you can avoid it but it is more work than downloading and compiling gmp). long (unsigned long). unsigned int 0～4294967295 (10位数，4e9) int -2147483648～2147483647 (10位数，2e9 2^31 - 1) long long： -9223 Those data are stored in memory locations. 다음 표에 지정된 범위는 포함-포함입니다. Depending on the programming language and the computer machine processor, the size of the long integer will vary. So other data types can be assigned to long without typecasting. The variable num2 has value 20. There seems to be several ways to use long: What is the difference between all of these various data types, and do they all have the same purpose? The keyword int may be omitted if any of the modifiers listed below are used. Description: Datatype for large integers. Format specifiers are also called as format string. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Refer the below program. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview … I'd say that on twentieth-century implementations for general-purpose reprogrammable microcomputers. [Edit: #include seems to be the proper way to ensure bitwidths using the int##_t types, though it's not yet part of the standard.]. In case of overflow or underflow of data type, the value is wrapped around. The int data type is a 32-bit signed two’s complement integer. Terms of Use and Privacy Policy: Legal. 4. While integers can be as large as 2,147,483,647 and as low as -2,147,483,648 (stored as 32 bits), a long integer has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (stored as 64 bits). long long (unsigned long long). Maximum value for an object of type unsigned long long int 18446744073709551615 ( 2 64 -1 ) or greater* * the actual value depends on the particular system and library implementation, but shall reflect the limits of these types in the target platform. The long type modifier can also be used with double variables. The types int and long when counted in bytes instead of bits the type int is 4 bytes and the type long is just twice if type int i.e. Here, we are going to learn how to convert long primitive type into int and Long object into int. What's the difference between long long and long. The keyword ‘long’ is used to declare a long. If int is 64-bits, then long will be. When definingint n;you could translate this with "give me the best compromise of bitwidth and speed on this machine for n". Java Convert int to long. 整數型別. It is required to be at least 32 bits, and may or may not be larger than a standard integer. If the variable is declared as an int, then he cannot assign a character value to it. int、long、long long取值范围 Pikachu_simple 2018-08-07 11:23:18 80364 收藏 37 分类专栏： C知识 文章标签： int long long C언어 각 데이터형 범위 입니다. For example, if 0 is stored in an unsigned long long int data type and 1 is subtracted from it, the value in that variable will become equal to 18, 446, 744, 073, 709, 551, 615. According to the above program, width and length are long variables. Long variables are extended size variables for number storage, and store 32 bits (4 bytes), from -2,147,483,648 to 2,147,483,647. char_bit : 8 char_max : 127 char_min : -128 int_max : 2147483647 int_min : -2147483648 long_max : 9223372036854775807 long_min : -9223372036854775808 schar_max : 127 schar_min : -128 shrt_max : 32767 shrt_min : -32768 uchar_max : 255 uint_max : 4294967295 ulong_max : 18446744073709551615 ushrt_max : 65535 Long integer. In the following example we are converting long data type to int data type using explicit typecasting. This doesn't necessarily mean that a long long is wider than a long. Similarly to the integral types, it's required to have at least as much precision as a double and to provide a superset of values over that type (meaning at least those values, not necessarily more values).
