***************************************** NOTE: See "My RPN Calc Ex" for the latest Windows 10 version that works on all Windows 10 desktops, surfaces, tablets, and phones. ***************************************** My RPN calculator is a scientific and financial calculator inspired by the Hewlett-Packard HP-10C series pocket calculators of the 80s, most notably the HP 12C and HP 15C models. These software version has borrowed the RPN (Reverse Polish Notation) and the look&feel of those calculators. It features classical 4 operations, logarithms, trigonometry, statistics, financial, and macros for easy programming. It also features complete support for complex numbers along with 2nd, 3rd, and 4th degree equations solving. Its unique magenta L key allows switching from one layout to another, thus saving space without compromising usability. While designed for touchscreen and mouse interactions, the application supports the physical keyboard for common operations. See the web pages of the application at http://calc.lsrodier.net for complete keys description and samples.
