Infinity and NaN aren't valid JSON, see http://www.json.org/. Unfortunately there isn't a way to specify those values in JSON.

Why is it invalid JSON? The following statement is true:

typeof Infinity === "number"

So it adheres to the specification in my Eyes.

By the way: JSON-Strings with Infinity and NaN *can* be converted to objects via eval().
