`abs`

---integer absolute value (magnitude)#include <stdlib.h> int abs(inti);

**Description**

`abs`

returns
the absolute value of `i` (also called the magnitude
of `i`). That is, if `i` is negative, the result is the opposite
of `i`, but if `i` is nonnegative the result is `i`.

The similar function `labs`

uses and returns `long`

rather than `int`

values.

**Returns**

The result is a nonnegative integer.

**Portability**

`abs`

is ANSI.

No supporting OS subroutines are required.
