This is a problem. Right now, in the trunk, math.float(1) returns 1, where it should return 1.0 for compatibility with 2.5. Jeffrey, can you fix this and similar incompatibilities you introduced?

Whoops! I've committed r59707 to fix math.{floor,ceil}. Let me know if you find any other problems. ... Hmm. I've also changed the behavior of round(2.5). I'll change that back tomorrow morning.

I haven't seen any answers to the original question. It looks like Decimal is decided by 2.5 too: return a float from everything. Rational, being a completely new type, is up to you guys, but because new support for the conversion routines seems to be rare, it's probably best to have it return floats too.
