About this app

The idea is to take the strengths of the HP48 calculator, and try to get the same capabilities but with a touch screen Android device instead. It is a little limited at the moment. Implemented features:
* arbitrary precision float (gmp/mpfr/mpc)
* good support for units
* RPN calculator
* basic scalar operations (sin/exp/etc)
* programmability (if you like FORTH or RPL)

Future features:
* vector/matrix math
* graphing
* base conversions

This is (hopefully) under heavy development so if you use it, let me know what you think. Also, let me know if you want access to my source repository.

Played with it a bit. Been searching for something like this. Can you try to add programming save/load? Would love it even more. It's basic on the language, needs some features.
