Excellent All Around Calculator for Working Engineers

Ive been switching over to Good Grapher Pro from a TI-86 emulator Ive used since my iPhone 3, since picking up this program in December. Im finding it pretty easily replaces everything Im used to doing.

Im a working EE, radio engineer, so I need complex numbers constantly. Good Grapher Pro handles them easily. I dont use the plotting capabilities at work,just to play with, and it seems pretty good with functions I know.

I have no negatives about the calculator, I just wish it had more features. Perhaps Im missing things, but built in metric conversions, and the ability to work with numbers in different bases (convert decimal to hex, and so on) would be nice additions.

Im also sensitive to the problems with putting too much on the already too small iPhone screen (compared to any iPad, that is).
