No but you can get the dot product of 2 vectors. The dot product is equal to the arccos for the angle (if the vectors are normalized). So to get the angle in degrees you can do something like:
var dot = vecA.dot(vecB);
var angleInRadians = Math.acos(dot);
var angleInDegrees = angleInRadians * pc.math.RAD_TO_DEG;
Usually though you don’t really need the angle in degrees you can solve your problem with less math… Depends on what exactly you’re trying to do…
