DIV(3C)
NAME
div, ldiv − integer division and remainder
SYNOPSIS
#include <stdlib.h>
div_t div (numer, denom)
int numer, denom;
ldiv_t ldiv (numer, denom)
long int numer, denom;
DESCRIPTION
The div function 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.
The ldiv function is similar to the div function, except that the arguments each have type long int and the result is returned in a structure of type ldiv_t (defined in stdlib.h) having long int members quot and rem for the quotient and remainder respectively.
WARNINGS
The behavior is undefined if denom is 0.
