    RPNCalc

    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.
