Apple's Open Source libm

Apple's Open Source project is a great resource for finding source code to use in your own projects. I've found many useful libraries and functions by browsing Apple's open source code - and I know they've been pretty-well vetted since they are deployed on OS X and iOS. All around, Apple Open Source is a very useful resource for developers bringing up a new system.

libm

Today I'd like to highlight Apple's libm implementation. This is a great resource for those who need math library functions on their platforms.

I usually wait until I need to implement some mathy things on my system before I worry about porting libm. Once I know what functionality I need, I import the specific functions into my project (usually with no changes). You can also just build the entire library and let the linker take out unneeded code for you.

Happy mathing!
