The constructor tries __trunc__ (truncate toward 0) if __int__ isn't defined. If __trunc__ doesn't return an instance of int, it calls the intermediate result's __int__ method. In terms of the numbers ABCs, numbers.Real requires __trunc__, which should return a numbers.Integral, which requires __int__. 

The special methods __trunc__, __floor__, and __ceil__ aren't documented in the language reference. They're mentioned briefly in the docs for the math functions trunc, floor, and ceil.
