I was e-mailed an interesting question, and that was whether or not if I knew there was a fast math programming library for the iPhone.

The answer to that is yes, I do know of one library which is known as the vfpmathlibrary.  The latest version of the library is included in the open source Oolong Engine.  Some extra compilation instructions can be found within the actual files themselves, and you can also look at how the Oolong projects are set up. 

A math programming library such as this one is somewhat beyond the scope of what this site is about, but for those interested in this level of optimization I found this blog post called VFP for noobs. I look forward to learning more, but have a long way to go.

From what I understand this library can provide a large increase in speed vs. the standard c math libraries so if you are pushing the envelope then it may be worth checking out.  At this point I have not seen the library used in the other open source iPhone game engines.
