public:
static double DistancePointPoint(
	double startX, 
	double startY, 
	double endX, 
	double endY, 
	[OutAttribute] double% angle
)

public:
static double DistancePointPoint(
	double startX, 
	double startY, 
	double endX, 
	double endY, 
	[OutAttribute] double% angle
)

Parameters

startX: Type: System Double
The x-coordinate of the start point.

startY: Type: System Double
The y-coordinate of the start point.

endX: Type: System Double
The x-coordinate of the end point.

endY: Type: System Double
The y-coordinate of the end point.

angle: Type: System Double
The angle of the line segment formed by the points.

Return Value

Type: Double

The distance between the points.

Remarks

Returns the length of the segment between (startX,startY) and (endX,endY) and optionally its angle.

The angle is measured in radians from the x-axis and is normalized to the range -π to π.
