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.
