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.

The author's website has all the source code for download:


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.
