Detailed Description

aring-style adapter for double-precision complex numbers, stored as (double, double) pairs.

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

ElementType is cc_doubles_struct — two IEEE-754 doubles for the real and imaginary parts. Holds a companion ARingRR mRR for the real-component arithmetic. ringID = ring_CC. Use ARingCCC instead when arbitrary precision is needed.
