rpCalc

rpCalc

rpCalc is a simple RPN (Reverse Polish Notation) calculator for the X Window System.

The software works much like an HP calculator, and all of the commands can be entered using the keyboard or a mouse.

If you know how to use an RPN calculator (like some Hewlett-Packard models), you know how to use rpCalc. It stores previous results in four registers (usually labeled X, Y, Z and T), and the numbers are entered before the operators.

rpCalc started out as a tiny program written to try out various Python GUI toolkits, but has evolved into a useful utility.
