Detailed Description

aring-style adapter for arbitrary-precision real numbers, backed by MPFR.

Note: AI-generated documentation. Verify against the source before relying on it.

ElementType is __mpfr_struct. mPrecision (set at construction) gives the bit precision used for every operation; characteristic is 0. ringID = ring_RRR. Forms the real component of ARingCCC.
