Yes, I had suspected as much. Intervals don't obey all of the rules that integers and reals do. For fun, I've tried to work out most of the principles of interval arithmetic for myself. There aren't many areas of modern mathematics where the topics are current, but where anyone other than a professional mathematician could get anywhere doing that. But now, I think I just want to finish my program library and have it be correct. I anticipate that looking at the HP49 library you mentioned will help a lot. Some of it might even be easily ported to the HP48 series. Daily drivers: 11c, 32sII, 35s, 41cx, 48g. Favorite: 16c. Current projects: WP 34s/31s. Gateway drug: 28s found in yard sale ~2009.
