Overview

Product summary

Review the store description, core capabilities, and common use cases.

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 should be ready for touch-screen chromebooks.

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 releases).

The initial goal of this extension was to be a real-life example of jQuery Mobile (and it worked as such) but somehow, with the time, more options were added and it became full-featured scientific calculator. It is, however, still work in progress, so let me know if you find a bug, if something isn't working or if you want to see new feature added.

Options:

There are 3 different “themes” for you too choose from. You can change the theme from the options page. Select between black, white or the original “3d buttons”. (Just click the “options” link at the bottom-right of the extension's popup and select the respective theme from the list)

Did not change image of calculator face on its own. Allows you to use the numbers keypad as well as mouse. In addition to the clear button, it also has a "Backspace" button. This one's "A Keeper"

Awesome. I like a pop-up calculator, nice interactions, and it can read keys from numpad. Very easy to use

It was nice, but when you try to use it, the calculator keeps on flashing.
