abs() computes the absolute value of its sourceNum argument. This is the non-negative value of sourceNum without regard to its sign. Thus both these result in a $MyNumber value of 3.5:

$MyNumber = abs(3.5); 

$MyNumber = abs(-3.5); 

The operator can also evaluate a numerical attribute:

$MyNumber = abs($SomeNumber); 

A numerical string attribute will be parsed to a number. If $MyString is a value of "-5", $MyNumber will be 5:

$MyNumber = abs($MyString);
