# div

## NAME

div, ldiv, lldiv - compute the quotient and remainder

## SYNOPSIS

#include <stdlib.h>

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

**ldiv_t ldiv**(**long int** *numer*, **long int** *denom*);

**lldiv_t lldiv**(**long long** *numer*, **long long** *denom*);

## DESCRIPTION

The **div()** function computes the quotient and remainder of the division of the numerator *numer* by the denominator *denom*. It provides a well-defined semantics for the signed integral division and remainder operations, unlike the implementation-defined semantics of the built-in operations. The sign of the resulting quotient is that of the algebraic quotient, and if the division is inexact, the magnitude of the resulting quotient is the largest integer less than the magnitude of the algebraic quotient. If the result cannot be represented, the behavior is undefined; otherwise, *quotient* * *denom* + *remainder* will equal *numer*.

The **ldiv()** and **lldiv()** functions are similar to **div()**, except that the arguments and the members of the returned structure are different. The **ldiv()** function returns a structure of type **ldiv_t** and has type **long int**. The **lldiv()** function returns a structure of type **lldiv_t** and has type **long long**.

## RETURN VALUES

The **div()** function returns a structure of type **div_t**, comprising both the quotient and remainder:

int quot; /*quotient*/

int rem; /*remainder*/

The **ldiv()** function returns a structure of type **ldiv_t** and **lldiv()** returns a structure of type **lldiv_t**, comprising both the quotient and remainder:

long int quot; /*quotient*/

long int rem; /*remainder*/
