NAME


div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer 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 quotient is rounded towards 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


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.

SEE ALSO


abs(3), remainder(3)
