There are vectors and matrices in the library: http://www.ada-auth.org/standards/12rm/html/RM-G-3.html I've no idea how well these optimise or perform for games / 3d rendering.
I have some old game optimised vector3/4 / matrix3/4 types I wrote for the NeHe ports I did. I don't even know if you need to optimise them now for the hw we have.
