ldiv(3) -- Linux man page
NAME
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer division
SYNOPSIS
#include <stdlib.h>
div_t div(int numerator, int denominator);
ldiv_t ldiv(long numerator, long denominator);
lldiv_t lldiv(long long numerator, long long denominator);
#include <inttypes.h>
imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);
DESCRIPTION
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() and 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.
RETURN VALUE
The div_t (etc.) structure.
EXAMPLE
After
div_t q = div(-5, 3);
the values q.quot and q.rem are -1 and -2, respectively.
CONFORMING TO
SVID 3, BSD 4.3, ISO 9899.
The functions lldiv() and imaxdiv() were added in ISO C99.
