MathF.Atan2(Single, Single) Method is used to return the angle whose tangent is the quotient of two specified numbers. Basically, it returns an angle θ (measured in radian) whose value lies between -π and π. This is a counterclockwise angle lies between the positive x-axis, and the point (x, y).
Syntax: public static float Atan2 (float y, float x);
y: The y coordinate of a point of type System.Single.
x: The x coordinate of a point System.Single.
Return Value: This method returns the angle Θ of type System.Single.
Note: An angle, θ(measured in radians), such that -π ≤ θ ≤ π, and tan(θ) = value1 / value2, where (value1, value2) are the points in the cartesian plane. There are two conditions for the return values:
- When the points lies in the Cartesian plane
- When the points lies on the boundaries of the quadrants
