Changes for version 0.42
- Remove gmp_v from Math::GMPf::V as we don't want any library functions in that module.
- Replace SvUV/SvIV/SvNV with SvUVX/SvIVX/SvNVX where appropriate. (In typemap, too.)
- Add Rmpf_get_NV and Rmpf_set_NV.
- Handle NOK/POK dualvars.
- Add Rmpf_set_IV, Rmpf_get_IV, Rmpf_fits_IV_p and Rmpf_fits_UV_p.
- Math::GMPf - perl interface to the GMP library's floating point (mpf) functions.
