	double x,
	bool isDegrees = false
)

Public Shared Function Circular ( 
	xValues As Double(),
	angles As Double(),
	x As Double,
	Optional isDegrees As Boolean = false
) As Double

public:
static double Circular(
	array<double>^ xValues, 
	array<double>^ angles, 
	double x, 
	bool isDegrees = false
)

static member Circular : 
        xValues : float[] * 
        angles : float[] * 
        x : float * 
        ?isDegrees : bool 
(* Defaults:
        let _isDegrees = defaultArg isDegrees false
*)
-> float 

Parameters

xValues  Double[]

The x-coordinates of the data points. Must be strictly increasing.

angles  Double[]

The angular y-coordinates of the data points (in radians by default).

x  Double

The x-coordinate at which to interpolate.

isDegrees  Boolean  (Optional)

If true, angles are in degrees; otherwise, radians.

Return Value

This method performs linear interpolation on circular/angular data by unwrapping the angles to minimize discontinuities and then wrapping the result back to the standard range.

Note: This method creates an internal PiecewiseInterpolatingCurve object for evaluation. This method should only be used for one-off calculations. For repeated evaluations on the same data, use CircularLinearCurve(ReadOnlySpan<Double>, ReadOnlySpan<Double>, Boolean) to create a reusable curve object, which will be more efficient.
