Problem seems to have been floating-point roundoff in XStringForFSB.toDouble(), 
rather than anything in the division. I've replaced that logic, and it seems to 
be significantly better. I'm not 110% sure results will always be a perfect 
match to the IEEE floating point standard we're supposed to be following -- 
floating point roundoff is always nasty -- but short of trying to assemble the 
bits ourselves it should be as close to perfect as we're going to get.

see the comments when I check it in for some open issues.
