  24     ECMA Section:       15.7.4.2.1 Number.prototype.toString()
  25     Description:
  26     If the radix is the number 10 or not supplied, then this number value is
  27     given as an argument to the ToString operator; the resulting string value
  28     is returned.
  29
  30     If the radix is supplied and is an integer from 2 to 36, but not 10, the
  31     result is a string, the choice of which is implementation dependent.
  32
  33     The toString function is not generic; it generates a runtime error if its
  34     this value is not a Number object. Therefore it cannot be transferred to
  35     other kinds of objects for use as a method.
