Angle calculation deviation issue

Hi Everyone, I am wrote this function to calculate the angle between vectors that ranges from 0-360. But for some reason, when the target vectors angle is more than 90 degrees the output shows angle value around 270 degrees.
Any Idea why this happening?

To avoid confusion use always a reference (i.e. a plane Z vect) for Vector3d.VectorAngle. See attached (and the Maths C#)
