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 numerator, long denominator);
lldiv_t lldiv(long long numerator, long long denominator);
#include <inttypes.h>
imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);
```

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

lldiv():

_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

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.

After

`div_t q = div(-5, 3);`

the values `q.quot`

and `q.rem`

are -1 and -2, respectively.

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