good calculator app? Hardcore = good

[NewGenAdam]

Did maths A level, and doing maths related uni degree.
The default calculator has lots of functions, but lacks one major ability.

Anybody know good calculator apps which have everything (indices, logs, pi, e, modulus etc), but which
you can enter long expressions into before equalling?
so put in 4^2+5/33-e^(1/pi) rather than dealing separately?

Thanks =D

HP is taking it's calculators of old and turning them into iPhone apps. not sure of the release date

Take a look at the 15c from HP, a modern day implementation of their 80s calc by same name (it uses the same ROM). One serious calculator (original manual was 290 pages!). it uses RPN so no need for parenthesis. Just enter stuff as you read it. Programmable too.

Expensive but awesome.

Any chance of you making this app universal? I would like this on my iPhone since it is with me a lot more often than my iPad.
