The ATAN2() function returns the arctangent value of the given coordinates.
Returns the arctangent of X- and Y- coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and the point (X-coordinate, Y-coordinate). This angle is expressed in radians.
A positive result represents a counterclockwise angle from the x-axis. A negative result represents a clockwise angle. When a > 0 and b > 0 or a > 0 and b < 0, the formula holds directly. When a < 0 and b > 0, ATAN2(a,b)=PI()-ABS(ATAN(b/a)). When a<0 and b<0, ATAN2(a,b)=ABS(ATAN(b/a))-PI(). When the return value is displayed in degrees, multiply the return value by 180/PI()to express it in radians (the return value is greater than -pi and less than or equal to pi).
ATAN2(-2,2) returns 2.356194490192345 (3 * PI/4 radians).
ATAN2(2,2) returns 0.785398163 (PI/4 radians)
