NAME

div(), ldiv(), lldiv(), imaxdiv( ) - integer division and remainder

SYNOPSIS

#include <stdlib.h>

div_t div(int numer, int denom);

ldiv_t ldiv(long int numer, long int denom);

lldiv_t lldiv(long long numer, long long denom);

#include <inttypes.h>

imaxdiv_t imaxdiv(intmax_t numer, intmax_t denom);

DESCRIPTION

div() Computes the quotient and remainder of the division of the numerator numer by the

denominator denom. If the division is inexact, the sign of the resulting quotient is that of

the algebraic quotient, and the magnitude of the resulting quotient is the largest integer

less than the magnitude of the algebraic quotient. If the result can be represented, the

result is returned in a structure of type

div_t (deﬁned in <stdlib.h> )having

members quot and rem for the quotient and remainder respectively. Both members have

type

int and values such that quot × denom + rem = numer. If the result cannot be

represented, the behavior is undeﬁned.

ldiv() Similar to div(), except that the arguments each have type longint and the result is

returned in a structure of type ldiv_t (deﬁned in <stdlib.h>) having longint

members quot and rem for the quotient and remainder respectively.

lldiv() Similar to div(), except that the arguments each have type longlong and the result is

returned in a structure of type lldiv_t (deﬁned in <stdlib.h> ) having longlong

members quot and rem for the quotient and remainder respectively.

imaxdiv() Similar to div(), except that the arguments each have type intmax_t and the result is

returned in a structure of type imaxdiv_t (deﬁned in <inttypes.h> )having

intmax_t members quot and rem for the quotient and remainder respectively.

WARNINGS

Behavior is undeﬁned if denom is zero.
