Detailed Description

aring-style adapter for double-precision real numbers.

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

ElementType is a plain double. Fixed precision (53 bits per get_precision()), characteristic 0. ringID = ring_RR. Hash values are derived from the double cast to unsigned int. Use ARingRRR instead when arbitrary precision is needed.
