Public Shared Function Atan (x As Single) As Single

Parameters

x: Single

A number representing a tangent.

Returns

Single

An angle, θ, measured in radians, such that -π/2 ≤ θ ≤ π/2.

-or-

NaN if x equals NaN, -π/2 rounded to double precision (-1.5707963267949) if x equals NegativeInfinity, or π/2 rounded to double precision (1.5707963267949) if x equals PositiveInfinity.

Remarks

A positive return value represents a counterclockwise angle from the x-axis; a negative return value represents a clockwise angle.

Multiply the return value by 180/MathF.PI to convert from radians to degrees.

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