We obviously are not referring to the same "Qalculate" application, or, it has been SIGNIFICANTLY improved.

and that snapshot doesn't even begin to do it justice.
How about differentiation and integration:

Hex conversions and calculations it can do, but that is a mere miniscule fraction of its capabilities.

Does it do statistical computations. Variance, standard deviation, reliability, correlation coefficient. I'm not doing it much anymore, but at one time I did a lot of it.

GG, yep the same Qalculate. I just wasn't clear in my post above and only introduced it in the context of number conversions. (With my math Master's + 2 years post, how could I fail to mention integral and differential functions! Ah, it was pure math that I spent my time on, that's why )

Qqmike, you're my kind of guy!!! 8) I love math and physics ALMOST as much as I love my wife, kids and grand kids.
