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. It features classical 4 operations, logarithms, trigonometry, statistics, financial, conversions tables, 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 on small displays like smartphones without compromising usability.
Support for gestures allows switching from one keyboard to another by swiping left or right, and a light swipe up or down on a key executes the associated f or g function, without any need to actually press the f or g key.
See the web pages of the application at http://calc.lsrodier.net for complete keys description and samples.
