math.atan2() function
The math.atan2() function returns the arc tangent of y/x, using the signs
of the two to determine the quadrant of the return value.
Output data type: Float
import "math"
math.atan2(y: 1.22, x: 3.14)
// Returns 0.3705838802763881
Parameters
y
The y coordinate used in the operation.
x
The x coordinate used in the operation.
Special cases
math.atan2(y:y, x:NaN) // Returns NaN
math.atan2(y: NaN, x:x) // Returns NaN
math.atan2(y: +0, x: >=0) // Returns +0
math.atan2(y: -0, x: >=0) // Returns -0
math.atan2(y: +0, x: <=-0) // Returns +Pi
math.atan2(y: -0, x: <=-0) // Returns -Pi
math.atan2(y: >0, x: 0) // Returns +Pi/2
math.atan2(y: <0, x: 0) // Returns -Pi/2
math.atan2(y: +Inf, x: +Inf) // Returns +Pi/4
math.atan2(y: -Inf, x: +Inf) // Returns -Pi/4
math.atan2(y: +Inf, x: -Inf) // Returns 3Pi/4
math.atan2(y: -Inf, x: -Inf) // Returns -3Pi/4
math.atan2(y:y, x: +Inf) // Returns 0
math.atan2(y: >0, x: -Inf) // Returns +Pi
math.atan2(y: <0, x: -Inf) // Returns -Pi
math.atan2(y: +Inf, x:x) // Returns +Pi/2
math.atan2(y: -Inf, x:x) // Returns -Pi/2
