labs : long integer absolute value

Synopsis

#include <stdlib.h>
long labs(long i);
```### Description

labs 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 abs uses and returns int rather than long values.### Returns

The result is a nonnegative long integer.
