They can also be used in place of int where their limits help to clarify your code; the fact that a variable’s range is limited can serve as a form of documentation.

Yes that is exactly why I am using the byte variable type. The final code is going to be used in a MIDI system where the maximum value I need to use is 127. So to check a valid value is being used all I need to do is check it is a positive number.
