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);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
lldiv(): _XOPEN_SOURCE >= 600  _ISOC99_SOURCE; or cc std=c99
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(), lldiv(), and imaxdiv() functions do the same, dividing num
bers 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.
CONFORMING TO
SVr4, 4.3BSD, C89. The functions lldiv() and imaxdiv() were added in
C99.
EXAMPLE
After
div_t q = div(5, 3);
the values q.quot and q.rem are 1 and 2, respectively.
