Description

Would be great to refactor the thing slightly so we can do code generation. Since conv actually have some internal buffer, I think the best way is to create a new NumberConverter class that contains the internal buffer, and move most of the methods there. And then in Conv expression, we just create a NumberConverter, and call it to do the conversion.
