div, ldiv, lldiv, imaxdiv − compute quotient and remainder of an integer division

**#include
<stdlib.h>**

**div_t
div(int** *numerator***, int**
*denominator***);
ldiv_t ldiv(long**

lldiv_t lldiv(long long

**#include
<inttypes.h>**

**imaxdiv_t
imaxdiv(intmax_t** *numerator***, intmax_t**
*denominator***);**

Feature Test
Macro Requirements for glibc (see
**feature_test_macros**(7)):

**lldiv**():

_XOPEN_SOURCE >= 600
|| _ISOC99_SOURCE ||
_POSIX_C_SOURCE >= 200112L;

or *cc -std=c99*

The
**div**() function computes the value
*numerator*/*denominator* and returns the quotient
and remainder in a structure named *div_t* that
contains two integer members (in unspecified order) named
*quot* and *rem*. The quotient is rounded toward
zero. The result satisfies
*quot***denominator*+*rem* =
*numerator*.

The
**ldiv**(), **lldiv**(), and **imaxdiv**()
functions do the same, dividing numbers of the indicated
type and returning the result in a structure of the
indicated name, in all cases with fields *quot* and
*rem* of the same type as the function arguments.

The
*div_t* (etc.) structure.

For an
explanation of the terms used in this section, see
**attributes**(7).

POSIX.1-2001,
POSIX.1-2008, C89, C99, SVr4, 4.3BSD. The functions
**lldiv**() and **imaxdiv**() were added in C99.

After

div_t q = div(−5, 3);

the values
*q.quot* and *q.rem* are −1 and −2,
respectively.

**abs**(3),
**remainder**(3)
