atan2()
Calculates the angle, in radians, between the positive x-axis and the ray from the origin to the point (y, x).
Syntax
atan2(y,x)
Arguments
- x: X coordinate (a real number).
- y: Y coordinate (a real number).
Returns
- The angle, in radians, between the positive x-axis and the ray from the origin to the point (y, x).
Examples
print atan2_0 = atan2(1,1) // Pi / 4 radians (45 degrees)
| extend atan2_1 = atan2(0,-1) // Pi radians (180 degrees)
| extend atan2_2 = atan2(-1,0) // - Pi / 2 radians (-90 degrees)
| atan2_0 | atan2_1 | atan2_2 |
