angle2()

This named function with three arguments calculates the angle between arrows defined by the first two arguments. The third argument is used to define the sign of the resulting angle. It is interpreted as an arrow which defines the rotation direction to rotate the arrow from the first argument to the arrow of the second argument. If this results in angles more than 180 degrees a negativ angle is given instead.
