Type:
• Number

The length of the vector that is represented by this point's coordinates.

Each point can be interpreted as a vector that points from the origin (x = 0, y = 0) to the point's location.

Setting the length changes the location but keeps the vector's angle.

Type:
• Number

The vector's angle in degrees, measured from the x-axis to the vector.

The angle is unsigned, no information about rotational direction is given.

Type:
• Number

The vector's angle in radians, measured from the x-axis to the vector.

The angle is unsigned, no information about rotational direction is given.

Type:
• Number

The quadrant of the angle of the point.

Angles between 0 and 90 degrees are in quadrant 1. Angles between 90 and 180 degrees are in quadrant 2, angles between 180 and 270 degrees are in quadrant 3 and angles between 270 and 360 degrees are in quadrant 4.

Type:
• Number

Example

var point = new Point({
	angle: 10,
	length: 20
});
console.log(point.quadrant); // 1

point.angle = 100;
console.log(point.quadrant); // 2

point.angle = 190;
