    Differential Calculator

    Differential Calculator

    Terminal calculator with differential error estimates

    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.

    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.
