div — compute the quotient and remainder of an integer division

Synopsis

#include <stdlib.h>

div_t div(int numer, int denom);

Description

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2008 defers to the ISO C standard.

The div() function shall compute the quotient and remainder of the division of the numerator numer by the denominator denom. If the division is inexact, the resulting quotient is the integer of lesser magnitude that is the nearest to the algebraic quotient. If the result cannot be represented, the behavior is undefined; otherwise, quot*denom+rem shall equal numer.

Return Value

The div() function shall return a structure of type div_t, comprising both the quotient and the remainder. The structure includes the following members, in any order:

int  quot;  /* quotient */
int  rem;   /* remainder */

Errors

No errors are defined.

The following sections are informative.
