Description:
HPCALC is an RPN (Reverse Polish Notation) calculator developed by Scott T. Schad, similar to the venerable HP-41.
Written in the PocketC programming language, HPCALC is both a handy utility and a learning tool for budding C programmers.
The program includes full source code and may be customized for non-commercial use.
Author's overview: I wrote HPCALC because I wanted a small, fast, RPN calculator for my Palm handheld, something like the old HP-41.
Other calculators for the Palm go overboard with too many features and shifted functions.
I kept HPCALC as simple as possible to provide basic math functions with the fewest pen taps.
I hope HPCALC spurs you to learn Jeremy Dewey's and Kevin Cao's delightful PocketC programming language! PocketC is available through Handango (do a search for "PocketC"), or from www.orbworks.com. New: fixed 1/x bug, shrunk startup screen.
