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 detailed User Guide to do a better job of explaining how to use RPNCalc. 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.
