Possible but not realy practical in any case when you need to do 1000's+ of FP 
operations, some of those been possibly quite complexe. And this was my point: 
maintain acceptable rendering speed while geting higher FP precision.
Arbitrary precision can be 100 to 1000 times slower, and possibly even worse.
