Command line calculator applications

Post by reavy »

What CLI apps are out there for calculators, particularly with RPN support? I am aware of bc and dc (the latter supports RPN input).

Are there HP-42s implementations/emulators/clones that run on a CLI, Linux or otherwise? Free42? Anything for HP-41CX? Or for that matter any of the other popular HP calculators?

I’m considering building a desktop calculator based on a Raspberry Pi with either an LCD character display or an eInk display. The thing would have practically unlimited storage and faster entry with an external keypad, e.g. a typical numpad.

Thanks in advance for any info or insight. Merry Christmas!

The idea of a command-line version of Free42 comes up every now and then, but I've never done one, since I don't see how one would work...

Yes, Craig Bladow is working on it since a few years with NQ41 and CC41.
Have a look here (https://www.hpmuseum.org/forum/thread-9616.html), and here (https://www.youtube.com/watch?v=CUvFmkcpVys).

Thanks Massimo, I've just released a CC41 update last week that utilizes the decNumber decimal library for 16 digit decimal math routines.
