Ask HN: Do you still use a hand held/desktop calculator?
There's also https://kalker.xyz. Not as powerful, but convenient syntax

Announcing arbitrary precision floating point numbers library.
I have been waiting for an alternative to rug for kalker for a long time now. I think this might be it soon.

Does anyone really like what Mathematica achieves, but hates the syntax?
For simple use-cases, I made a program called kalker which handles syntax like f(x) = 2ax(x + 2)(a - sqrt2) with syntax highlighting in the REPL and auto completion to mathematical symbols. In many cases you can write math like you would write it on paper. Right now I'm about to release support for vectors, matrices and numerical root-finding.

Ask HN: Do you still use a hand held/desktop calculator?
No, I use a Python interpreter that is always open in tmux on the first tab. I have a bunch of predefined functions that I use a lot: https://github.com/orlp/dotfiles/blob/master/pcalc/pcalc
The killer pre-defined functions? copy(x) and paste(). You can guess what they do.

PCalc, an Origin Story
I have a program always open called pcalc as well, but it's something homebrew and short for Python calculator. It's just a Python repl (enhanced by python-prompt-toolkit) with a bunch of my own pre-defined functions: https://github.com/orlp/dotfiles/blob/master/pcalc/pcalc
I use it all the time, it's so incredibly useful. My most used pre-defined functions are... copy(s) and paste(). E.g. doubling a comma-separated list of numbers is one simple
copy(", ".join(x*2 for x in eval(paste())))
