fix: floating-point number serialization issue for non-normal values #992

Closed filzrev closed 2 weeks ago

filzrev commented 1 month ago

This PR intended to fix #991.

What's changed in this PR

Replace formatter.FormatNumber(object value); call to ToString("G", CultureInfo.InvariantCulture).
- It's required to serialize special symbols (Nan/PositiveInfinite/NegativeInfinite) to JSON compatible string representation.
- Additionally explicitly specify format (G) to align YAML serialized value
Remove NumericRegex checks. Instead add IsNaN/IsInfinity checks
Add unit test code (SerializationOfNumericsAsJsonRountTrip)
