Jovial Reverse Polish Notation Calculators

JRPN Reverse Polish Notation Calculators inspired by the HP-15C and HP-16C

If you are using Android and have an interest in RPN calculators, I highly recommend RpnCalc. No ads, no tracking, just a great calculator.

Thanks! I'm currently using DozeCal (which defaults to base 12 on every launch, which is fun, but not usually what I want), and 48sx, which is cool but I don't know how to use it well, and some common actions are buried.

concatenative

@programming.dev

Hello!

This space is for sharing news, experiences, announcements, questions, showcases, etc. regarding concatenative programming concepts and tools.

We'll also take any programming described as:

pipelined
stack-oriented
tacit
postfix / reverse Polish notation (RPN)
fluent
cascading
chained

From Wikipedia:

A concatenative programming language is a point-free computer programming language in which all expressions denote functions, and the juxtaposition of expressions denotes function composition. Concatenative programming replaces function application, which is common in other programming styles, with function composition as the default way to build subroutines.

For example, a sequence of operations in an applicative language like the following:

y = foo(x)
z = bar(y)
w = baz(z)

...is written in a concatenative language as a sequence of functions:

x foo bar baz

Let me know if I've got any of these misplaced!
