I was thinking the same thing while reading the article. I have been using RPN calculators for 40 years, and it has become second nature to manipulate the stack to have two calculations going at the same time, and then merging them, if needed.
- bollu 4y agoWhat's the RPN based calculator you use on your terminal? I'd love to learn!
- self 4y agodc, perhaps.
- dr-neptune 4y agoNot sure what the parent uses, but emacs has calc, which is a RPN calculator with lots of features (including history and intermediate results) and can be used in the terminal
- deepspace 4y agoTo be honest, I mostly use a physical calculator (Swissmicros DM41L, which is an HP41CX clone). Second choice is the i41CX+ app on my phone. The HP41 keyboard and operational patterns were etched into my brain at university, since my first engineering calculator was an HP41C. I have used rpncalc and T_REX (https://isene.org/2021/02/T-REX.html https://isene.org/2021/02/T-REX.html) in the terminal, dc or gforth in a pinch.
