[]
This function calculates the arctangent of the specified x- and y-coordinates.
ATAN2(x, y)
This function has these arguments:
Argument | Description |
|---|---|
x | [Required] The x-coordinate of the point |
y | [Required] The y-coordinate of the point |
The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates ( x , y).
The result is given in radians between –PI and PI, excluding –PI. If you want to convert the result to degrees, multiply the result by 180/PI.
ATAN2(A1,E3)
ATAN2(R1C1,R3C5)
ATAN2(1,1) gives the result 0.7853981634
