ABS()


Syntax:     ABS(<expN>)

Purpose:    To evaluate a numeric expression and return the absolute
            value.

Argument:   <expN> is a numeric expression to evaluate.

Returns:    A numeric value.

            ABS() returns a positive number or zero for any numeric
            expression argument, whether positive or negative.

Usage:      ABS() is used wherever you need to know the magnitude of a
            numeric expression.  This allows you to evaluate the
            difference between two numbers when you are not concerned
            with the sign of the result.
