Changes for version 0.30
- Add Rmpf_snprintf and Rmpf_snprintf_ret.
- Fix test 18 in test1.t. (It *was* checking the first 96 bits of two 64-bit numbers for equality ... which seems a bit dubious, and not always be guaranteed to succeed.)
- Math::GMPf - perl interface to the GMP library's floating point (mpf) functions.
