handling infinity values in JSON

Question

I need at one place to have the support for infinity, -infinity and NaN values in my JSON. Now though JSON does have support for these values, but is there any support for speci

Answer 1

JSON does not support neither infinity or NaN values (and never has, since the original json.org grammar). Neither does JSON Schema (because it is only defined for RFC8259-compliant JSON documents or structures).

This is due to interoperability reasons - otherwise each target language that does not support infinities or NaNs would need to always wrap these values.

Whether some validator accepts invalid json documents - does not really matter. They are still invalid.
