Where xn is the x-coordinate and yn is the y-coordinate of that particular point
ATAN2 returns the error value when both xn and yn are 0.
If you want to convert the arctangent in degrees, multiply the result by 180/PI.
Calci returns the arctangent of the particular x- and y-coordinates. It is the angle from the x-axis to a line with origin (0, 0) and with coordinates (xn, yn).
