Frankly, I don't get it. In my reading of the standard, either when val is set
or val is not set, when in == end at the end then we have eofbit. Maybe you
should simply attach a testcase where the behavior is incorrect, the provided
one is fine (and consistent with the general behavior for numeric parsing).
