   File Name:          15.8.2.1.js
   ECMA Section:       15.8.2.1 abs( x )
   Description:        return the absolute value of the argument,
   which should be the magnitude of the argument
   with a positive sign.
   -   if x is NaN, return NaN
   -   if x is -0, result is +0
   -   if x is -Infinity, result is +Infinity
