The actual sizes of short int, int, and long int are available as the constants short max int, max int, and long max int etc. ^b Commonly used for characters. ^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short , int , long , and ( C99 , C++11 ) long long , so they are implementation-dependent.
Some conversions between types (e.g., between the various integer types) are pre-defined and adding a new type may define additional conversions, but conversions between named types must always be invoked explicitly. [68] For example, the type keyword can be used to define a type for IPv4 addresses, based on 32-bit unsigned integers as follows:
Convert to an int32 (on the stack as int32) and throw an exception on overflow. Base instruction 0x84 conv.ovf.i4.un: Convert unsigned to an int32 (on the stack as int32) and throw an exception on overflow. Base instruction 0xB9 conv.ovf.i8: Convert to an int64 (on the stack as int64) and throw an exception on overflow. Base instruction 0x85
C code should prefer (u)intptr_t instead of long when casting pointers into integer objects. A programming model is a choice made to suit a given compiler, and several can coexist on the same OS. However, the programming model chosen as the primary model for the OS application programming interface (API) typically dominates.
Integer addition, for example, can be performed as a single machine instruction, and some offer specific instructions to process sequences of characters with a single instruction. [7] But the choice of primitive data type may affect performance, for example it is faster using SIMD operations and data types to operate on an array of floats.

Conversely, precision can be lost when converting representations from integer to floating-point, since a floating-point type may be unable to exactly represent all possible values of some integer type. For example, float might be an IEEE 754 single precision type, which cannot represent the integer 16777217 exactly, while a 32-bit integer type ...
