   3     Corresponds To:     15.7.4.2-2-n.js
   4     ECMA Section:       15.7.4.2.2 Number.prototype.toString()
   5     Description:
   6     If the radix is the number 10 or not supplied, then this number value is
   7     given as an argument to the ToString operator; the resulting string value
   8     is returned.
   9
  10     If the radix is supplied and is an integer from 2 to 36, but not 10, the
  11     result is a string, the choice of which is implementation dependent.
  12
  13     The toString function is not generic; it generates a runtime error if its
  14     this value is not a Number object. Therefore it cannot be transferred to
  15     other kinds of objects for use as a method.
