Watch out:
1970*5844 (11,512,680) - 11,512,692 = minus 
There is right-shift for the minus.

True. But I left it like that, because in this case it doesn't affect the result.


But here it does, so the array is of a different type.

I am not feeling comfortable with mixing variables types here. Surely it'll cause problems as I dont understand how this expression gets evaluated.
 
Thank you for sharing this amazing work.
 
very good and educative base on time accuracy and performances
