Serhiy, nobody is proposing to add float.as_integer().  It already exists:

>>> (3.1).is_integer()

I already allowed I don't have a feel for how _generally_ useful it is, but you have at least my and Stefan's word for that the functionality (however spelled) _is_ necessary in implementing various math libraries.

If we outlawed float functions that the numerically naive may misuse, we'd have to remove floats entirely.

Given that it's _already in the language_, the only question here is whether to make it play nice with types beyond just `float`.  I expect you'd have a hard time constructing an example where int.is_integer() returned a misleading result ;-)
