20.1.1 The Number Constructor
...
The Number constructor is designed to be subclassable. It may be used as the
value of an extends clause of a class definition. Subclass constructors that
intend to inherit the specified Number behaviour must include a super call to
the Number constructor to create and initialize the subclass instance with a
[[NumberData]] internal slot.
