About this app

Programmer's calculator that simulates an HP 16C. It simulates the appearance and behavior of the original, including the seven-segment display, and the little blink you get when entering numbers. The 16C's windowing functions are implemented, but can be disabled to allow the display of longer numbers at one time.

Full source is available on Github. There is no advertising of any kind -- this is a hobby project, and a bit of a labor of love.

Do be aware that the 16C is a calculator intended for computer programmers. If you're not familiar with hexadecimal or stack-based RPN calculators, this probably isn't what you're looking for!

Reviewed moments after download. I have one of these for real bit the screen died unfortunately. This works just as well with the asthetic I like. The cherry on top is the inclusion of the back panel. Absolutely perfect. Thank you for keeping this tech history alive and making a very functional app.

Beautifully executed calculator. It looks and works great! Thank you very much for sharing your work and helping to keep RPN alive and well. (Thanks to Emmett, too, for letting you use his code.)

Anyone who spends a huge amount of time doing this kind of thing as a labo(u)r of love deserves 5 stars. On top of that, it's emulating my favourite calculator. Thanks a million.
