Specification: ZZRingElem (OSCAR v1.6-v1.8)

Profiles: OSCAR v1.6, OSCAR v1.7, OSCAR v1.8 Other versions: ZZRingElem (OSCAR v1.0-v1.5)

From OSCAR v1.6 onward, elements of ZZ are encoded as parametric typed values that make the ambient ring explicit.

Encoding rules

• Use a typed _type object with name: "ZZRingElem".
• Record the ambient ring in _type.params, typically as {"_type": "ZZRing"}.
• Store the value under data as a decimal string.
