float llVecMag(vector vec)Returns the magnitude (geometric length) of vec.vector llVecNorm(vector vec)Returns the normalized unit vector pointing the same direction as vec. If <0, 0, 0>, return <0, 0, 0>.vector llRot2Fwd(rotation q)Returns the unit vector pointing toward positive X (forward) in the coordinate space of rotation q. Equivalent to <1, 0, 0> * q.
