PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface
may differ (consult the corresponding 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.1‐2017 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.
