25    Description:        return the absolute value of the argument,
26                        which should be the magnitude of the argument
27                        with a positive sign.
28                        -   if x is NaN, return NaN
29                        -   if x is -0, result is +0
30                        -   if x is -Infinity, result is +Infinity
