Clever stuff. If you're interested in such things, best book I've seen is "Hackers Delight" http://www.amazon.com/Hackers-Delight-Henry-S-Warren/dp/0201...

Author covers really clever techniques to count bits, count non zero bytes like this etc etc. Bit manipulation at its best.

Holy crap, all 15 reviews of that book are 5 stars! That's the best average I've ever seen on Amazon.

I'd give it 5 also. It's a ridiculously clever fun book.

I agree with some of the reviewers though, the title probably means less people manage to find it than if it was called "Bit manipulation bible" or something.
