It is a minor detail, but why are you shifting both side of the
operator? It is really confusing, cannot you just do 1<< X?
With 0< X< 13.
I can change this if it is confusing to others.
So you are still convince that this is a good way to do it???
What is the rational behind that?
Why adding potential source of confusion when you can avoid that easily?
