It's minor but I don't love this. Especially when we're compiling to JS, which
doesn't distinguish between ints and doubles, it seems gratuitous.

I don't know if this is a symptom of a more general issue, or if this really
just occurs with int and double. 

     if (parsed == null) parsed = double.parse(normalizedText);
     return parsed / scale;
   }
