Not really -- __int__ is expected to return something of type

Scratch that, it seems __trunc__ also returns an int, at least
for floats. Not sure what the logic behind that is.
There are differences between the functions int() and trunc()
though:
>>> int("42")
42
>>> trunc("42")
Traceback (most recent call last):

TypeError: type str doesn't define __trunc__ method
Conceptually, I would say that int() is a type conversion,
whereas trunc() is an operation on numbers. A type would be
entitled to implement them both but differently.
