When I wrote Fracton I used doubles because I had to support Intel and PowerPC processors on the Mac. I wanted both processors to give the exact same result and long doubles were different between the two processors. Now that Mac's have used Intel processors exclusively for almost 10 years I guess I could improve normal math precision by using long doubles. I still have arbitrary precision for all formulas if you want it (and are willing to put up with the huge speed hit) so I don't gain any functionality. This explains why FractInt sometimes had more resolution than Fracton when using normal math. Thanks for taking the time to explain it. -- Mike Frazier www.fracton.org
