    File Name:          15.7.4.3-1.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.
