Examples of computeAngle()

chunmap.model.elem.Angle.computeAngle()
计算三点之间的夹角,顺时针或共线时为正，逆时针为负,异常时返回0
net.sf.latexdraw.glib.models.interfaces.shape.IPoint.computeAngle()
Computes the angle of the given point where the calling point is used as the gravity centre. @param pt The point used to compute the angle. @return The angle or NaN if the given point is not valid.
