Besides, I'd be willing to bet a class (or several) have already been made. There is also a problem with your example usage of FixPoint. By initializing the FixPoint with a float you are still at risk for rounding errors. It would be better to initialize a FixPoint from integers or a string if accuracy is truly paramount.
