Issue with isAntiparallelTo(vector) documentation

Reading the api documentation for vector, under isAntiparallelTo() method it says: "Returns true iff vector’s direction is exactly opposed to that of the receiver, that is, if the angle between them is π." Wouldn't exactly opposite be π/2?

No, π is 180 degrees, π/2 is 90 degrees. An angle of π/2 would make them perpendicular, not antiparallel.

I'm sorry, brain fart!
