Methods

AreClose(double, double, double)

Determines whether the two specified values are close within the order of tolerance.

public static bool AreClose(double value1, double value2, double tolerance)

Parameters:value1double

The first value.

value2double

The second value.

tolerancedouble

The allowed tolerance.

Returns:

bool

AreClose(double, double)

Determines whether the two specified values are close within the order of EPSILON.

public static bool AreClose(double value1, double value2)

Parameters:value1double

The first value.

value2double

The second value.

Returns:

bool

GetArcPoint(double, RadPoint, double)

Gets the point that lies on the arc segment of the ellipse, described by the center and radius parameters.

public static RadPoint GetArcPoint(double angle, RadPoint center, double radius)

Parameters:angledouble

The arc segment angle.

centerRadPoint

The center of the ellipse.

radiusdouble

The radius.

Returns:
