/**
File Name: 15.7.4.3-3.js
ECMA Section: 15.7.4.3.1 Number.prototype.valueOf()
Description:
Returns this number value.
The valueOf function is not generic; it generates a runtime error if its
this value is not a Number object. Therefore it cannot be transferred to
other kinds of objects for use as a method.
