Thank you, that seems like it should work. I was concerned about the
rounding of the first double, but if I subtract it from the
high-precision value again any rounding error will be restored in the
second double.  I'll have to think of a way to do higher exponents.

Do you know if inclusion of long long or long double is something coming
to GMP?
