Log of base 2 calculator

Simply because I found myself needing to work out the log of base 2 for a series of numbers whilst studying and comparing several 'divide and conquer' algorithms, I decided to write a simple log of base 2 calculator. You can try it by following the link below.

As you can see from the screenshot, the applet keeps a record of all of your calculations until you refresh the page and the results are returned with 15 decimal places accuracy.

It is hoped that the page will be of use to students of computer science, mathematics, or any of the natural sciences that require logs of base 2. It is also hoped that the app will be of use to anyone who simply loves their powers of 2 (and who doesn't?).
