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.
