I noticed the FloatVectorOperations class while looking for ways to speed up some things. Is there is a best practice for using this in code that may be run cross-platform (desktop, phones, ipad, etc.)? It may be simple and just work, but I did not want to take anything for granted. I searched for a tutorial but could not find one.
The best-practice is just "use them"!
The whole point is that they'll do the best thing possible on whatever platform you're using. Not much else to say about it, really!
