This is a J2ME Feature phone port of my Android version of scientific calculator. Take note that feature phones comes in various shape and sizes (memory, display size, physical shape, keyboard/keypad types) from lowly 1MB 2G QQ-VGA grayscale flip-phones all the way up to J2ME aware Symbian with touchscreen and hardware that rivals a smartphone.
With such hardware disparity in mind, this program has no peripheral features that its Android counterpart has, only a fully-featured core set with the ability to define variables. This calculator is simple enough for anyone to use, if you know only public-school arithmetic, chances are you know how to use it.
I invite you to load the built-in examples to learn how to use the app to its fullest.
