The JSON RFC ( http://tools.ietf.org/html/rfc4627 ) states that NaN, Positive Infinity and Negative Infinity cannot be represented in JSON:
Numeric values that cannot be represented as sequences of digits (such as Infinity and NaN) are not permitted.
I don't know where you're getting 1*10^309 from, because Javascript's maximum exact integer value is 2^53.
When you say "concise" do you actually mean "succinct"?
