Hello.. i have 2 problems... i'd be very grateful if anyone could help me.. 1. some expressions return very complex expressions (e.g. when u solve a third degree equation), you get a very complex formula for the result. i am looking for a way to output the result in a human-readable format (like 2.3342218) not with many roots, and stuff like this, how can i do it? 2. how can i find the point on a chi squared distribution where the CDF will be 0.995? thank you very much in advance... yours... msdawy
