Out of curiosity, while I often see "no, arbitrary-precision floats 
won't be done in POV ever because they're way too slow", it's never 
really indicated just how slow this would be.  Slower than hardware, to 
be sure, but that's not much to go on.  Current *single* CPUs can do in 
seconds what took hours or days fifteen years ago...in software.

I, for one, would be interested in seeing hard number comparisons.
