Specification: Rational Numbers (OSCAR v1.0-v1.5)

Profiles: OSCAR v1.0, OSCAR v1.1, OSCAR v1.2, OSCAR v1.3, OSCAR v1.4, OSCAR v1.5 Other versions: Rational Numbers (OSCAR v1.6-v1.8)

In OSCAR v1.0 through v1.5, rational numbers are encoded with the bare type name "QQFieldElem" and a textual fraction payload.

Encoding rules

• Use _type: "QQFieldElem".
• Store the rational value under data using a textual fraction such as "42//23".
• The ambient field is implicit in the type name.

Canonical Example Payload

The following payload is taken directly from the current rosetta-stone corpus.

{
  "_ns": {"Oscar": ["https://github.com/oscar-system/Oscar.jl", "1.5.1"]},
  "_type": "QQFieldElem",
  "data": "42//23"
}
