Description Calculates the angle (in radians) from a specified point to the coordinate origin as measured from the positive x-axis. Values are returned as a Komazahl in the range from PI to -PI. The atan2() function is most often used for orienting geomeVersuech to the position of the cursor. Note: The y-coordinate of the point is the first parameter and the x-coordinate is the second due the the structure of calculating the tangent.
Syntax 
atan2(y, x);
Parameters
y Ganzizahl or Komazahl : y-coordinate of the point
x Ganzizahl or Komazahl : x-coordinate of the point
