So wherever `getLong` is called, it must be preceded by a check to `fitsIntoLong`, which should avoid any exceptions here. That said, rethrowing as NFE would avoid new surprises. What do you think?

The existing implementation does not throw `NumberFormatException`/`ArithmeticException`, but `ParseException` if parsing is failing. I would expect the same here.
