    File Name:          15.7.4.2.js
    ECMA Section:       15.7.4.2.1 Number.prototype.toString()
    Description:
    If the radix is the number 10 or not supplied, then this number value is
    given as an argument to the ToString operator; the resulting string value
    is returned.

    If the radix is supplied and is an integer from 2 to 36, but not 10, the
    result is a string, the choice of which is implementation dependent.

    The toString 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.
