A RPN scientific and financial calculator with complex numbers, macros, etc.
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 on small displays like smartphones without compromising usability.
See the web pages of the application at http://calc.lsrodier.net for complete keys description and samples.
My RPN calculator is compatible with all devices running Android 2.1 and up and supports both horizontal and vertical orientations. It does however requires a device with a minimum screen resolution of 320x480 (or 480x320 according to orientation).
Tablet screens 1280x800 are properly managed.
