I would probably use +0 as well, but writing double() explicitly is clearer to people about what is being done and why. People tend to expect that adding 0 will leave everything unchanged...

In the forum if I'd bothered to do the conversion I'd've added a comment on the purpose. As was, I figured the expression alone did satisfy the question and the remainder could be "exercise for the student"...
