RPN calculators for Linux

Back to:

There's another rpn calculator: "pcalc". You find it on my web pages at (Perl Version).

It is console based, and has 10 memory places with labels!
On program exit it writes a save file, so it looks the same after restart.

The RPN calculator that I really like is, calculat.pdf

Yip you read it right, it's a .pdf file. Truely awesome
and cross-platform. ;)

Enjoy, Louis.

which is forgot to mention: rpc
The homepage of rpc is here:

Nice article. I'd forgotten how much I prefer RPNs to infix. Now I need to track down some apps...

and now I have several to choose from!

xcalc and has also an rpn mode:
xcalc -rpn

Simple but very good!

Just for the people that might find this page via google. :)

Regards, Louis.

The RPN I have used for 20 years seems to be on its last legs. Can they be repaired? I have looked at several stores in our area - Best Buy, Staples, Radio Shack, Office Depot but I have not been able to find any. What stores do carry the RPN's? I live in Wilmington, DE.

I'm surprised nobody mentioned calc.el (see ) . I pressed this into service quite hard when doing some financial work for my family, and use it when I pay my bills. It also maintains a 'paper tape', and with a single keystroke ('y'), will copy the result of a calculation into the current text buffer.

Many thanks for your excellent review of RPN software for Linux. It is very helpful.

P.S. to Ted Modi: My advice is to buy an HP-12C. Some office stores carry it, but it may be most easily available via the Web.

I've been looking for a really portable and powerful RPN calculator and I've found it. The Forth language !!

RPN calculators are inspired in the ancient Forth language. Forth is small but extremely powerful and there are interpreters and compilers for almost any computer in the world.

Thanks for this article. I've read it more than a time and is really useful.

When I started college in 1981, my Dad, an MSEE, bought me an HP-15C. In 1995 I spilled a glass of milk on it. I got an HP-48, and subsequently an HP-49G; but I just can't get over how perfect that 15C was. It was so easy. Calculators now are so complicated. You have to go through menu after menu to do one little thing. I wish HP would make the 15C again. They would probably make a lot of money on it. I think that is pretty much what people really want in a calculator.
