Fast inverse square root



Found this while browsing about the net, and I thought it could be useful (or at least an interesting read). Lengthy explanation, for the mathematically inclined.

This is really interesting; I skimmed through the research paper, probably give it a closer look a bit later. I've covered Newton's method in the recent pass; probably one of the most important computational approximation methods in existence, but it was very interesting reading how they derived that constant. I'll need to remember this function so I can use it later projects.

Thanks!
