I would like to learn how to break a byte down to it's bit level. So i can access that one bit to settings. Similar to the Constant techinques found in openGL and Max2D collision system.

00000001 = 1
00000010 = 2
00000100 = 4

I can add these values together

00000111 = 7

Those numbers never need to "carry" so i can use 8 boolean switches for settings.

I remember looking up the math for it before. Kinda forget it though. I want to go to bed so..can you help me. Thanks for you time :D.
