div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an
div_t div(int numerator, int denominator);
ldiv_t ldiv(long numerator, long denominator);
lldiv_t lldiv(long long numerator, long long denominator);
imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
lldiv(): _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; or cc -std=c99
The div() function computes the value numerator/denominator and returns
the quotient and remainder in a structure named div_t that contains two
integer members (in unspecified order) named quot and rem. The
quotient is rounded towards zero. The result satisfies
quot*denominator+rem = numerator.
The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing
numbers of the indicated type and returning the result in a structure
of the indicated name, in all cases with fields quot and rem of the
same type as the function arguments.
The div_t (etc.) structure.
SVr4, 4.3BSD, C89. The functions lldiv() and imaxdiv() were added in
div_t q = div(-5, 3);
the values q.quot and q.rem are -1 and -2, respectively.
