DIV(3) Linux Programmer's Manual DIV(3)NAME
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an inte‐
ger 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 quo‐
tient is rounded towards zero. The result satisfies quot*denomina‐
tor+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
SVr4, 4.3BSD, C89. The functions lldiv() and imaxdiv() were added in
C99.
