About this app

see https://github.com/gilles-fabre/O3 for the source code and example scripts.

O3 stands for O.perand O.perand O.perator, based on the Reverse Polish Notation input method.

O3 supports basic calculations using the digits pad and the stack, but it does much more... see the 'About menu' for more information about the scripting language, graphical capabilities, programmable buttons, debugging features, etc.
