Open Source Mac RPN Calculators

This project has created scientific firmware for the HP-20b and HP-30b business calculators. WP 34S turns either of these calculators into a powerful keystroke programmable scientific device. According to our customers, it's the most powerful and fastest RPN scientific pocket calculator ever built. WP 34S is alive and stable since 2011. We have succeeded in satisfying the most picky users - read about their experiences on http://www.hpmuseum.org/forum/forum-8.html. Since 2014, WP 34S runs in version 3.3. Our customers confirm its documentation is excellent and comprehensive (see feedback); a full-color printed edition is available from https://www.amazon.com/dp/153366238X since 2018-10-15. Alternatively, you can get a personalized pdf-manual for a ≥ 9 US$ donation here. We have also produced the WP 31S which is derived from the WP 34S source code. This is an entry-level scientific calculator. Its printed manual is available from https://www.amazon.com/dp/1499231164 .

Calcoo is a scientific calculator (with both RPN and algebraic modes) designed to provide maximum usability.

OpenDRO is an open source project to develop embedded software that runs on digital readouts (DROs) for lathes, mills, and other machine tools.

Some end user utilities for the Windows operating system. The utilities can be called thru the "Send To" context menu when right-clicking on a file or directory in the explorer or thru the Windows "Start Menu". The package can be 'installed' portable and does not need admin rights. ◆ 𝗨𝗧𝗜𝗟𝗜𝗧𝗜𝗘𝗦 - https://sourceforge.net/projects/wa2l-wintools/files/ → README ◆ 𝗙𝗘𝗔𝗧𝗨𝗥𝗘𝗦 - https://wa2l-wintools.sourceforge.net/man1/wintools.1.html - https://wa2l-wintools.sourceforge.net/man1/wintoolsintro.1.html ◆ 𝗣𝗔𝗖𝗞𝗔𝗚𝗘 𝗗𝗢𝗖𝗨𝗠𝗘𝗡𝗧𝗔𝗧𝗜𝗢𝗡 - http://wa2l-wintools.sourceforge.net/ ◆ 𝗦𝗘𝗘 𝗔𝗟𝗦𝗢 🚩 - https://sourceforge.net/p/wa2l-wintools/wiki/Home/ ◆ 𝗣𝗔𝗖𝗞𝗔𝗚𝗘 𝗙𝗢𝗥𝗠𝗔𝗧 The package is distributed in the following format: - WA2LWinTools-<VERSION>-<DATE>.exe (self extracting zip file) ◆ 𝗢𝗧𝗛𝗘𝗥 𝗣𝗥𝗢𝗝𝗘𝗖𝗧𝗦 - https://sourceforge.net/projects/wa2l-simplebackup/ - https://sourceforge.net/projects/wa2l-edrc/ .

TRURL is a suite of desktop calculators with reverse Polish notation (RPN) written in Object Pascal. Additionally, it comes with a free reusable class library (RPN Engine) as a toolbox for creating your own calculator. TRURL is an acronym for "TRURL is a Reusable Universal RPN Library". Class Libraries: • RPN Engine: Full-featured calculation engine for Pascal-based RPN calculators • Segmitator: Library for virtual seven-segment displays Applications: • TRURL A: Simple demo app for the RPN Engine • TRURL B: RPN calculator in the design of the famous calculators by Dieter Rahms for Braun • TRURL G: Desktop RPN calculator inspired by the UI of the DSKY unit of the Apollo Guidance Computer (AGC)

Baculator is a Reverse Polish Notation (RPN) calculator program with an infinite scrollable stack and support for most common mathematical operations as well as some more esoteric operations. Available for Unix/Gtk+, Mac OS X, and MS Windows.

The purpose of the CoCalc project is to develop a simple RPN calculator application for use on laptops running OS X. It has been developed in Cocoa and Objective C, although it may change to a PyObjC application in the future.

This collection of ASCII games has been split into a) SliderPuzzles & b) RetroArcade . CoTerminalApps is a collection of ASCII games & puzzles. that can run on Windows, Mac/OSX, & Linux. Includes SpaceInvaders, Pacman & Frogger arcade games and an RPN calculator.

A calculator that solves many types of problems including solving equations computing derivatives and integrals simplifying expressions graphing equations 2d and 3d reverse polish notation, algebraic and word based interpreter infinite writing board for writing out equations requires java 11 or more

This is a terminal calculator with a remarkable twist. It uses symbolic differentiation to provide a numerically precise error estimate with each calculated answer. It mimics the functionality of an HewlettPackard ReversePolishNotation [RPN] calculator simply because I like RPN. But along with your answer, you get some measure of its trustworthiness. Runs on PCs or laptops running Windows or Linux.

This application emulates an HP25c RPN calculator on a BlackBerry Storm/Storm 2. It is 100% compatible with the classic pocket calculator of the late 1970s, is fully programmable, and will include a program librarian to save and recall user programs.

HorsePower is J2ME scientific calculator optimised for use on mobile phones, with the appearance of the classic range of Hewlett Packard calculators. (MIDP 1.0 & CLDC 1.0)

This terminal app runs on PCs or laptops running OSX or GNU/Linux. It attempts to mimic the functionality of an HP ReversePolishNotation [RPN] calculator with the added enhancement of interval output. So along with your answer, you get a good idea of its trustworthiness. This app uses GAOL, a C++ library to perform arithmetic with floating-point intervals.

An RPN calculator in Java with a minimalistic interface, designed to be stylish, complete and useful.

An open source RPN calculator written in C

REPCAL (REverse Polish CALculator) is a light and fast calculator in RPN (reverse polish notation) mode for the console (command line). It is written in 180 lines of Python code, and can be used both interactively or inside shell scripts.

This is a Reverse Polish Notation (RPN) Fraction Calculator. It works like any other RPN calculator, except that it operates on fractions instead of decimal numbers. Decimal number entries are not permitted. Whole numbers are permitted.

Reverse Polish Notation interpreter for use as an interactive calculator in conjunction with the standard Python interactive interpreter. Easily extended by the user.

RPNCalc is the command-line based Reverse Polish Notation (RPN) calculator. RPN calculators make it very simple to do complex calculations, especially if there are parentheses involved. I've created a User Guide (https://frossm.github.io/RPNCalc-UserGuide) to do a better job of explaining how to use RPNCalc than the old readme.md file, which was getting really long. If you have questions, issues, feedback, or ideas, please let me know. You can contact me via the links in the **Introduction** page of the User Guide. ## RPNCalc User Guide: https://frossm.github.io/RPNCalc-UserGuide ##

NO LONGER MAINTAINED HERE - GONE TO https://gitlab.com/wef/gdcalc gdcalc is a financial, statistics, scientific and programmers calculator for Unix and Linux. The GUI was written with glade(1) and uses the Gnome/Gtk-2 toolkit - so it may well be compatible with themes and other whiz-bang features of those systems. gdcalc has both Algebraic notation (ie. conventional, TI or Casio style) and Reverse Polish Notation (RPN or Hewlett-Packard style). If you've not heard of RPN before, you are probably familiar with algebraic calculators. Very briefly, while simpler and more natural to use, RPN calculators need some study eg. they have an Enter key instead of the equals key.

Reverse Polish Notation (RPN) calculator for PNG images.

kalc is a programmable scientific calculator, using RPN (Reverse Polish Notation). Its behaviour imitates a HP48/HP49 calculator. Works with real and complex numbers, unlimited size integers, arbitrary-precision real numbers and more.

Not much more to say. This is just a test bed for MonoDevelop projects which might later take on a life of their own. The first project here is to make a productivity / project administration program, which I am calling RBMhelper. When it becomes alpha stage, I'll move it over to my other project repository with that name. "miniTimer" is a basic count up /down timer. "miniCalc" is a basic RPN calculator. "GTDtimer" is a timer with additional dialogs to help you Get Things Done. This tool will be one of a collection of tools to be used in the separtate project known as "RBMhelper", by abudeveloper also.

rpnstring has a small amount of command by it self. Instead it provide interface to the C math library. The user can make own commands by using the macro facility. In that way the calculator can be adapted to each user according to the users needs.

An RPN calculator for vectors of arbitrary dimension. Supports multiple undo/redo, programmable macros and variables. Saves/loads stack to/from disk. Lots of built-in scalar, vector, stack functionality.
