I think Dennis has well tackled the divide by 0 problem.
I programmed it simply checking to see if the dividing bits were zero
and then not calculating the indicator if they were.
But can I ask what benefit adding the Average function has? I've simply
been using it in its native format according to the formula he gives on
p 148.
