Taking into consideration that POVRay uses double precision floating 
point values (at least as built on intel platforms, others may vary) 
there are 52 mantissa bits. In normalised form, this yeilds actually 53 
bits of precision (the first bit is implied to be 1) which gives a 
maximum representable whole number of: 9,007,199,254,740,992

Depending on how many digits to the right of the decimal point you'll 
need, You'll have to move that decimal to the left a bit. (Keeping in 
mind what POVRay needs is dependant on what type of object you are 
attempting to trace. I'd at least cut the number of digits in half. 
90,071,992 would probably be a safe bet, but really it depends on 
whether or not there's enough headroom for the root-solver.
