Hi,
Aaargh, sorry about that, temporary brain-fart on my behalf.

At the moment I'm afraid I can't come up with an alternative solution. I'm sure there is one though and hopefully someone else will jump in.

I've never used the floating point routines and I don't really see any reason to do it here. N-Bit math might be an option but I currently don't have the time to do the experiments for you so you're going to have to try it yourself. Darrels examples in the thread is pretty self explainatory.
