The complex class has special methods which always raise a TypeError:


After removing them the corresponding operations (converting to int and float, operators // and %, function divmod()) will still a TypeError.

Advantages of removing:

* Less code to maintain.
* More uniform error messages.
* Clearer output of help().
* Possibility to implement a type with __rfloordiv__, __rmod__ and __rdivmod__ which support complex numbers.

The docs for this should probably be updated to reflect the change:

Indeed, Bartosz. Do you think you can help by submitting a PR for the docs?

Done so:

Signed the CLA thing too, it seems it'll take a while to update tho.
