NAME
abs( ), labs( ) - return integer absolute value
SYNOPSIS
#include <stdlib.h>
int abs(int i);

DESCRIPTION
abs() returns the absolute value of its integer operand.
labs() is similar to abs(), except that the argument and the returned value each have type
long
int.
The largest negative integer returns itself.
WARNINGS
In two’s-complement representation, the absolute value of the negative integer with largest magnitude is
undefined. Some implementations trap this error, but others simply ignore it.
