Double Dabble

July 31, 2018

Over at ComputerPhile, Professor Brailsford gives a beautiful explanation of the double-dabble algorithm for converting a number from binary to binary-coded decimal. If you don’t want to watch the video — you should — there is also an explanation at Wikipedia, or you can read the original description by C. B. Falconer.

Your task is to implement the double-dabble algorithm as shown by Professor Brailsford. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
