public:
 static float Atan2(float y, float x);
public static float Atan2 (float y, float x);
static member Atan2 : single * single -> single
Public Shared Function Atan2 (y As Single, x As Single) As Single

Parameters

y
Single

The first number.

x
Single

The second number.

Returns

The angle whose tangent is the quotient of y and x

Remarks

The return value is the angle in the Cartesian plane formed by the x-axis, and a vector starting from the origin, (0,0), and terminating at the point, (x,y).

This method calls into the underlying C runtime, and the exact result or valid input range may differ between different operating systems or architectures.
