About:
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, units support, base conversions, command completion, configurable keybindings, and a visible interactive stack.

[»] Outstanding!

Orpie is the program I've been trying to get time to write. Now I don't have to! Thanks for bringing a console rpn calculator that behaves like an HP calculator. I've always liked my HP48GX, now I have a version I can use anywhere!

I totally agree. It's the only decent calculator that can do complex arithmetic and linear algebra over ssh, short of a mathematics package. Very clean, very nice. It would rock if someone did an embedded version !
Of course, it is written in Ocaml - what else ?

For what it's worth, Orpie does have a pretty clean separation between the UI code and the underlying calculator object. The calculator object can be imported into other OCaml code pretty easily; there's an example of this in calc_test.ml .
