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
