I think I've found some gems in the iPhone OS (iOS 4).  

I found that there're 128-bit, 256-bit, 512-bit and 1024-bit integer data types, provided by the [Accelerate Framework](https://developer.apple.com/iphone/library/navigation/index.html#section=Frameworks&topic=Accelerate "Accelerate Framework Reference (iOS Reference Library)"). There're also Apple's implementation of Basic Linear Algebra Subprograms (BLAS), Apple's implementation of LAPACK (Linear Algebra PACKage), and Digital Signal Processing (DSP) routines.  

I'm so excited because BLAS and LAPACK are the best (and the most famous) libraries as far as I know. (In case if you've never heard their names, just Google them and you'll understand.) They let you solve simultaneous linear equations (i.e. **A**x = **b** in vector / matrix notation), do fast matrix multiplications, and more.  

I'm quite sure that the libraries are available on both PowerPC- and Intel-based Mac's. However, when I look up the "What's new in iOS4" documentation in Xcode, it says that the data types are "not supported on any architecture". When I compare the [vecLib Reference for Mac OS X](http://developer.apple.com/mac/library/documentation/Performance/Conceptual/vecLib/Reference/reference.html "vecLib Reference (Mac OS X Reference Library)") and [vecLlib Reference for iOS](http://developer.apple.com/iphone/library/documentation/Performance/Conceptual/vecLib/Reference/reference.html "vecLib Reference (iOS Reference Library)"), I also found that functions are missing in the iOS version.  

**My question is:**  

Has anyone compiled any program using these libraries (bignum is my primary area of interest) and run them successfully on a real iPhone device? (Answerers who can demonstrate their actual experience on the librarie(s) are more appreciated.)
