real_from_mpfr() [1/2]

void real_from_mpfr ( REAL_VALUE_TYPE * r, mpfr_srcptr m, const real_format * format, mpfr_rnd_t rndmode )

extern

Convert from MPFR to REAL_VALUE_TYPE, for a given format FORMAT and
rounding mode RNDMODE.  FORMAT is only relevant if M is a NaN.

real_from_mpfr() [2/2]

void real_from_mpfr ( REAL_VALUE_TYPE * r, mpfr_srcptr m, tree type, mpfr_rnd_t rndmode )

extern

Convert between MPFR and REAL_VALUE_TYPE.  The caller is
responsible for initializing and clearing the MPFR parameter.   

Convert from MPFR to REAL_VALUE_TYPE, for a given type TYPE and rounding
mode RNDMODE.  TYPE is only relevant if M is a NaN.
