Definition: The absolute value of a number is the distance between the number and 0, and is always a positive number. In math it is usually depicted as two vertical lines like this: |X| (the absolute value of X.) In PHP we use the Abs () function to get this value.
Also Known As: Absolute Value Function
Examples:
<?php
abs (-6) ;
//returns a value of 6
abs (12.4) ;
//returns a value of 12.4
abs (-456.2) ;
// returns a value of 456.2
?>
