If you are willing do spend some time at it, you could try using GNU MP:
http://gmplib.org/
It may require some tweaking to get it working on ODE though.



More than once I thought about adding a dGMP (other than dSINGLE and
dDOUBLE), to make calculations using "mpf_class". But getting the
epsilons right might be difficult. I'll give it a try next time I have
some free time.
