//description:
//useful math functions for analyzing vectors, note that these all use angles in radians (just like the cos/sin functions) not degrees unlike makevectors/vectoyaw/vectoangles, so be sure to do the appropriate conversions (multiply by DEG2RAD or RAD2DEG as needed).
//note: atan2 can take unnormalized vectors (just like vectoyaw), and the function was included only for completeness (more often you want vectoyaw or vectoangles), atan2(v_x,v_y) * RAD2DEG gives the same result as vectoyaw(v)
