JSCalc – the JavaScript calculator bookmarklet

JSCalc is a bookmarklet that creates a calculator on top of any web page that you are currently viewing. Just activate the bookmarklet and start typing in the figures that you need to calculate – add up prices, figure out percentages, determine the 24th decimal of Pi; anything you can count.

Right-click here and "Bookmark" JSCalc to access it anywhere, or click the link to try it out.

Note: due to Internet Explorer's restriction upon URL lengths this bookmarklet will not work in that browser. It is only guaranteed in Mozilla or Firefox.

You can view the uncompressed JavaScript code here.
