orpie is a curses-based RPN calculator.
The interface is similar to that of modern Hewlett-Packard calculators, but has been optimized for efficiency on a PC keyboard. The design is also partly influenced by the Mutt email client and the Vim editor.
orpie doesn’t have graphing capability, nor does it offer much in the way of a programming interface.
This is free and open source software.
