Thanks for clarifying.  It was a faulty assumption on my part.

It IS true that you should keep your numbers in the same range for the 
greatest accuracy.  As I was unaware of the internal limits imposed by 
POV-Ray, I assumed this range difference was the culprit, and therefore 
I assumed that the limit had been reached.

Really what I should have said was, "It's a known aspect of the hardware 
we use that you should keep your ratios within a reasonable limit to 
avoid precision errors, and I'm assuming that you have reached that limit."

Of course he hadn't yet reached that limit, but instead had run into 
POV's internal limits.
