H.2.2 Integer types

H.2.2.1 Integer operations

The signed C integer types int, long int, long long int, and the corresponding unsigned types are compatible with LIA-1. If an implementation adds support for the LIA-1 exceptional values “integer_overflow” and “undefined”, then those types are LIA-1 conformant types. C’s unsigned integer types are “modulo” in the LIA-1 sense in that overflows or out-of-bounds results silently wrap. An implementation that defines signed integer types as also being modulo need not detect integer overflow, in which case, only integer divide-by-zero need be detected.

The parameters for the integer data types can be accessed by the following:

maxint        INT_MAX, LONG_MAX, LLONG_MAX, UINT_MAX, ULONG_MAX,
              ULLONG_MAX
minint        INT_MIN, LONG_MIN, LLONG_MIN

The parameter “bounded” is always true, and is not provided. The parameter “minint” is always 0 for the unsigned types, and is not provided for those types.
