You're thinking about it the wrong way. It's
operation(float,float) -> float. It just happens
that if you give it two ints, they get promoted
to floats by the normal coercion rules before
the operation.

It's just the same as sqrt(int) -> float, etc.
I've never heard anyone complain that
math.sqrt(5) doesn't return 2, for instance...
