I suppose it depends on what the purpose of your Fraction class is. Is your goal to create an exact representation of a fraction like 1/3? Or will you be satisfied with convenient alternatives like 0.3333333333? If it's the former, I would use only exact integer types for the numerator and denominator - int, long, or BigInteger. Floating-point arithmentic frequently has small roundoff errors; it's inherent in the format. If you're OK with approximations - then why do you need ths Fraction class at all? For computations you might just as well convert everything to doubles. However, you may have some other reason for this class, which I am unaware of. Care to provide more details on what you're trying to do?

I'm currently playing with Squeak, a modern Smalltalk dialect. Smalltalk has a Fraction class and uses it fully transparently since ages.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
