ATAN2

ATAN2 - This function return the inverse tangent of the specified x and y coordinates. This function gives the angle between the line passing through some point and the origin with the x-axis. The value that is returned is in radians.

Syntax:
ATAN2(number_x;number_y)

number_x - value of the x-coordinate
number_y - value of the y-coordinate

Example:
Suppose we have the point (10,20). What is the angle between the line passing through the given point and the origin with the x-axis.

=ATAN2(10,20) will return 1.10714872
