How to convert decimal to unsigned binary in JavaScript

Ok, I do have to admit that this has limited value. I did this mostly as a thought experiment. I wanted to see how easy it would be to script the conversion from decimal to binary and back again, in JavaScript.

 

 

As you can see, the conversion from binary to decimal is much easier than decimal to binary. Before you ask, I do know that toString() can convert decimal to binary, octal, and hexadecimal but that would not have been as fun. šŸ™‚

Edit: I updated BinaryToDecimal(). There was a significant flaw in it. After talking the problem over with Jeremy Streich, I also decided that this could be refactored to be much more simple. I’ll probably wait on writing a revision, though. I want to try hex and octal sometime soon and I’ll revisit this as part of that.
