DIV(3) Linux Programmer's Manual DIV(3)
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer divi-
sion
#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 || _POSIX_C_SOURCE >= 200112L;
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
toward 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 C99.
After
div_t q = div(-5, 3);
the values q.quot and q.rem are -1 and -2, respectively.
abs(3), remainder(3)
