  24     ECMA Section:       15.7.4.3.1 Number.prototype.valueOf()
  25     Description:
  26     Returns this number value.
  27
  28     The valueOf function is not generic; it generates a runtime error if its
  29     this value is not a Number object. Therefore it cannot be transferred to
  30     other kinds of objects for use as a method.
