div(3) Library Functions Manual div(3)
NAME
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an inte-
ger division
LIBRARY
Standard C library (libc, -lc)
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():
_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
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 toward 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.

HISTORY
POSIX.1-2001, C89, C99, SVr4, 4.3BSD.
lldiv() and imaxdiv() were added in C99.
EXAMPLES
After
div_t q = div(-5, 3);
the values q.quot and q.rem are -1 and -2, respectively.
