Sometimes I wonder if since Python supports dynamic typing of results, might not do better by removing the NaN value from Floats and Decimals, and make the operations that generate the NaN generate an object of a special NaN type.

I don't see what problem that would solve. All it would do is enable us to claim that the float type was totally ordered, without technically lying. Any operation on floats would still be able to return a NaNType value that would get mixed in with your other float operations, so it would make no practical difference. -- Greg
