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

real_from_mpfr() [1/2]

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

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.

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

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.
