RPNCalc
RPNCalc - The command line Reverse Polish Notation (RPN) Calculator
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 ## -

PraktiCalc
a practical calculator written in Python
PraktiCalc is a simple calculator written in Python, compatible with Windows 7+ and Linux. MacOS support is also here now, in form of an unsigned .app bundle. There are not that many actually useful functions provided by PraktiCalc which don't exist in a modern calculator. But you have support and integration for Linux and Windows, especially for messagebox dialog tools like zenity, kdialog and xmessage on Linux and VBS MsgBoxes on Windows. All that together with number conversion and great DPI scaling, it can be great and it will be even better in the future. -
