Case
- Goal
- Serialize negative zero as -0 and preserve IEEE 754 negative zero during YAML parse and stringify round-trips HOW
- Packages
- yaml 2.8.2
- Environment
- node

Contract
- assert YAML.stringify(-0) outputs '-0\n' rather than '0\n'
- assert YAML.stringify({ offset: -0 }) formats the property value as -0
- assert YAML.parse('-0') returns JavaScript -0 distinct from +0 via Object.is
- assert 1 / YAML.parse('-0') yields -Infinity
- assert a round-trip YAML.parse(YAML.stringify(-0)) preserves the negative zero sign
