  26     Description:
  27
  28     The Number prototype object is itself a Number object (its [[Class]] is
  29     "Number") whose value is +0.
  30
  31     The value of the internal [[Prototype]] property of the Number prototype
  32     object is the Object prototype object (15.2.3.1).
  33
  34     In following descriptions of functions that are properties of the Number
  35     prototype object, the phrase "this Number object" refers to the object
  36     that is the this value for the invocation of the function; it is an error
  37     if this does not refer to an object for which the value of the internal
  38     [[Class]] property is "Number". Also, the phrase "this number value" refers
  39     to the number value represented by this Number object, that is, the value
  40     of the internal [[Value]] property of this Number object.
