I recommend calc, I fell in love with RPN and can’t use normal calculators anymore. Never heard about sunrise commander though.

  I occasionally need a calculator, but I just evaluate elisp expressions in *scratch*. What am I missing by not using calc?

    Fewer keypresses. RPN input is very efficient that way. Something like (sqrt (log (* 3 (+ 9 7))) in calc is "9 RET 7 + 3 * L Q". (Sorry about the bad example, I'm short on time.)

      Thanks, that makes sense, especially the avoiding parenthesis part.

  Same here. I knew about RPN before Calc, and knew there were calculators that used it, but it seemed bizarre to me. Once I started using Emacs, I decided to see what Calc was all about, and finally realized how slick it feels. It's really cool to need to do some math while coding or writing, hit a quick keybind, and have a full-fledged calculator right in my editor. And the cool part is you can do things algebraically, too. Even solve for variables. Really crazy program.
