One different calculator (pop-up version) ...
This is kinda unusual scientific calculator.
What makes it unusual is that you can see both sides of the current binary operation. For example -- if you type 2 + 2 you'll see exactly "2 + 2" until you press "=". The tool was made with touch-screen in mind and is optimized for small devices (10" tablets and netbooks).
The way it works (showing both left and right operand at the same time) means that if you have an operation entered (for example: 5 * 6) and tap some unary operation button (for example the square button) the operation will be performed on the second operand (in our example 6 will become 36).
On devices with keyboard you can use the obvious keys: number keys, dot (floating point), +, -, *, /, Enter (=), ESC (C) and BackSpace. The advanced ("scientific") functions are not yet accessible with keyboard shortcuts (but better keyboard support is planned for the next release).
The initial goal of this app was to be a real-life example of jQuery Mobile (and so far it looks like it works). Please, let me know if you find a bug, if some operation isn't working or if you want to see new feature added.
There are two different versions of the same app in the store -- this one (extension that will add a quick-start icon at the top-right of your Chrome browser) and stand-alone app version (that opens in it's own browser tab). Feel free to install both versions to see which one best fits your needs.
