This snippet is for DBC, to make it compile in DBP change the & to &&.

I was just looking at this and going "Considering it's DBC, I bet he's doing some convoluted math to get it done rather than simply checking the first bit in the integer." I'm pleasantly surprised

Everything I needed to know about trigonometry, I learned by becoming a game programmer.
