Fullscreen RPN calculator for the console
Orpie is a fullscreen RPN calculator for the console. Its operation is similar to that of modern HP calculators, but data entry has been optimized for efficiency on a PC keyboard. Features include extensive scientific calculator functionality, command completion, and a visible interactive stack.
Orpie is the successor of math/rpc by the same author; it has been completely rewritten in Ocaml, and offers a number of features that were not available in the older program.
