# Low level bit hacks

I came across a fascinating article on Peteris Krumins blog using boolean operators to perform handy low-level bit hacks.

Most people are used to just using AND and OR operators on integers, but this article goes into much more detail, explaining good – and fast – ways to manipulate integers at a bit level.

- Check if the integer is even or odd.
- Test if the n-th bit is set.
- Set the n-th bit.
- Unset the n-th bit.

And many more. It is well worth it to go and Introduction to Low-Level Bit Hacks.
