Convert null from JSON deserialization to NaN for Number type in Actionscript
Raw
null_to_NaN.as
// In Actionscript, a null result from a JSON service reponse will be converted to 0.0 default when casting to a number.
// What we really want is NaN:
var rs:Object = service.result; // Result deserialized from some JSON service
var value:Number = rs.value_num == null ? NaN : rs.value_num;
