CartesianAngle extension

Extensions for Angle objects that introduce Cartesian concepts.

Clockwise and Counter-Clockwise: You might wonder why CW and CCW properties are defined here, rather than on Angle, itself. Consider that when you look at a device screen, positive angles move clockwise. When you look at a mathematical graph, positive angles move counter-clockwise. An angle in isolation cannot know whether it is CW or CCW. Thus, this directional concept is tied to a particular Cartesian orientation.

Methods

direction([CartesianOrientation orientation = CartesianOrientation.screen]) → AngleDirection

Returns AngleDirection.clockwise if this Angle is clockwise within the given orientation, or AngleDirection.counterClockwise otherwise.

isClockwise([CartesianOrientation orientation = CartesianOrientation.screen]) → bool

True if this Angle represents a clockwise arc, or zero.

isCounterClockwise([CartesianOrientation orientation = CartesianOrientation.screen]) → bool

True if this Angle represents a counter-clockwise arc, or zero.

makeClockwise([CartesianOrientation orientation = CartesianOrientation.screen]) → Angle

Returns a clockwise version of this Angle.

makeCounterClockwise([CartesianOrientation orientation = CartesianOrientation.screen]) → Angle

Returns a counter-clockwise version of this Angle.
