PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
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 divi-
sion 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 fol-
lowing members, in any order:
int quot; /* quotient */
int rem; /* remainder */
ERRORS
