Synopsis

#include <stdlib.h>

div_t div(int numerator, int 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():

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 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.

Return Value

The div_t (etc.) structure.

Conforming to

Example

After

div_t q = div(-5, 3);

the values q.quot and q.rem are -1 and -2, respectively.
