Your approach is certainly different from that fixed-point approach, but mostly due to lack of time in comprehending it I'm not yet sure that I see where you are going with it other than implementing your own 128-bit floating point numbers?

Um. I'm just playing with it at the moment. Looking for the path of least resistance that allows me to get back to what I really want to be doing.

I reasoned that as I have a 64-bit scale (it costs no more in computation time than using a byte; and I only have 6 of these numbers, so the extra space isn't an issue), it was easier to allow the scale to float a little than getting into doing "proper" fixed point and the need for a 128-bit register.

That maybe short-sighted, but I've never written anything like this before, so I don't know what limitations I'm going to encounter. A new world to explore :)

Maybe your links will educate me against it.

Lot's to watch and read. Many thanks for your help.
