4    ECMA Section:       15.7.4.3.1 Number.prototype.valueOf()
5    Description:
6    Returns this number value.

8    The valueOf function is not generic; it generates a runtime error if its
9    this value is not a Number object. Therefore it cannot be transferred to
10    other kinds of objects for use as a method.
