jnpntime for some concatenative language
dnparadiceMore work on my pure #python #rpn #calculator. I added the ability to edit user functions for the calculator with syntax highlighting thanks to the IDLE editor.
SiliciumJ’adore ces machines où l’UX est… mécanique.
La HP-46 (1973) combine calcul scientifique, RPN et imprimante intégrée : tu obtiens une trace papier immédiate et le clac-clac vaut un ASMR vintage. 😄

KodsnackRPN - rätt sätt att räkna på.
Joachim Klahr använder omvänd polsk notation i sitt programmeringsspråk Quadrate, och insåg att han räknat på ett sämre sätt hela livet.

...Вот именно поэтому для подсчтета всякой бытовой херни у меня есть какулятор в обратной польской нотации 😉 Всё лежит в стеке, нет «алгоритмического» порядка операций 😉 нету скобок, понятно даже ребенку с первого раза. На #FDroid гуглить RPN Calculator, вот этот самое огниво при том, что прост как три копейки.
☮ ♥ ♬ 🧑💻@futurebird User of HP calcs since the 80s, not everyones cup of tea. #RPN: Removal of parenthesis during calculations. Having operators before and after operands to calculate arbitrary expressions translates to speed and clarity of input.

Droppie [opensoc]@bitzero i went to uni in the late 70s to early 80s, & i was in the opposing camp... i chose to swap my hitherto #sliderule for a TI-59, with its dinky little magnetic cards & internal motor, + #RPN also, ofc. several of my friends also bought the same one, though one went for the TI-58. other friends did go the HP route, specifically the HP-41C iirc. fun times.
TRURL Team"All Hewlett-Packard pocket calculators feature RPN logic- the most sensible logic system a pocket calculator can have!"
This beautiful short introduction to #RPN (Reverse Polish Notation) is from Hewlett-Packard's Pocket Calculator Buyer's Guide printed in 1975.
The MINUTEMAN * 6X was an early calculator by #Commodore from 1974, the company that was later famous for legendary computers like the Commodore 64 and the #Amiga family. The #MINUTEMAN supported #RPN (reverse Polish notation), had a 2-level stack and arithmetics for integers and currency values.
