Scheme also has a built in rational number type. There's been some discussion of building that in to Python, but my understanding is that's being left to libraries at this point. We already have any number of Rational Number implementations (I've written a few myself).
Rationals are easy to implement and easy to understand from a mathematical POV, but not practical when it comes to computing your taxes. ABC used rationals and it was not a success (except amongst mathematicians :-). Floating point decimal is a much better choice. -- --Guido van Rossum (home page: http://www.python.org/~guido/)
