#### NAME

div - compute the quotient and remainder of an integer division

#### SYNOPSIS

`#include <stdlib.h>`

div_t div(int *numer*`, int` *denom*`);`

#### DESCRIPTION

^{[CX]} 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 IEEE Std 1003.1-2001 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.*

#### EXAMPLES

#### APPLICATION USAGE

#### RATIONALE

None.

#### FUTURE DIRECTIONS

None.
