Buy a different machine, one that doesn't adhere to IEEE 754 (I'm not
sure these exist anymore), or use a different program that does slower
multiprecision computations in software, not in hardware.
If you're having problems with precision, the solution is usually to
understand hardware floats and roundoff error. Quarteroni, Sacco &
Saleri has a nice discussion of the problem in chapter 2. If you don't
have a copy available in the library, let me know, and I can think of
other ways to help you.
