title: iOS help: math.h? Where is this?
body: <p>I am following a tutorial out of a book and in the .h file of where some of my code is, I have to type in: #import . Where is this file located? Is it part of some framework or do I have to download it somewhere? I've googled this and found a question about math.h on MacRumors, so I know that it has something to do with iOS programming and probably isn't specific to the book.</p>
