You maintain heading as instructed and report it as 345. When was the last time you heard any vectors from Air Traffic Control ending in anything other than a zero or five? ATC only work to the nearest five degrees (two degrees difference - which is the most it will ever be provided you've rounded the right way - isn't going to make any difference and in the unlikely event it does, ATC can give you a further heading change). I've had this discussion with controllers many a time.
Epic thread drift, which is what I feared by making the comment in the first place, so apologies!
