The perfect RPN calculator. Works perfectly. Full keypad and keyboard support. A pleasure to use.

I love the size and shape of the calculator. I can snap the app to the side and use it easily with other apps. Some functions require getting used to (x^y requires the user to input the exponent before the base), but otherwise it works beautifully.

Is there a way to run this on the desktop, so that I can see other applications while using the calc?

RetroCalc works well, but constantly consumes ~50% of CPU time.

This calculator is cleanly laid out and easy to use. The macro feature is a nice addition, and is easy to figure out even without a help screen. It inherits the HP35's inability to warn of an overflow error. Just remember that 99.999E99 is "infinity-overflow." Also, remember that the trig functions work in degree mode only. More annoyingly, division by 0 always yields 0. The original HP35 would also display zero, but would flag the error by flashing the display. That feature is missing from RetroCalc. I would give RetroCalc a higher rating if div/0 were flagged (since that feature existed in the original microcode), and if the inherent limits (i.e. overflow, no radian mode) were explained on a help screen.

Can use number pad and "Enter" to enter numbers, but can't hit + multiple times to add the stack. .NET Rpn Calculator, even tho it crashes on exit, is still the best.

I appreciate the faithful rendition, but for actual use a higher-precision mode would be nice. Try the test: 9 sin cos tan arctan arccos arcsin
