Namespace:  Accord
Assembly:  Accord (in Accord.dll) Version: 3.8.0 Syntax
```[SerializableAttribute]
public struct DoublePoint```

The DoublePoint type exposes the following members. Constructors
NameDescription DoublePoint
Initializes a new instance of the DoublePoint structure.
Top Methods
NameDescription  Add(DoublePoint, DoublePoint)  Add(DoublePoint, Double) DistanceTo
Calculate Euclidean distance between two points.  Divide
Division operator - divides coordinates of the specified point by scalar value. Equals
Check if this instance of DoublePoint equal to the specified one.
(Overrides ValueTypeEquals(Object).) EuclideanNorm
Calculate Euclidean norm of the vector comprised of the point's coordinates - distance from (0, 0) in other words. GetHashCode
Get hash code for this instance.
(Overrides ValueTypeGetHashCode.) GetType
Gets the Type of the current instance.
(Inherited from Object.)  Multiply
Multiplication operator - multiplies coordinates of the specified point by scalar value. Round
Rounds the double precision point. SquaredDistanceTo
Calculate squared Euclidean distance between two points.  Subtract(DoublePoint, DoublePoint)
Subtraction operator - subtracts values of two points.  Subtract(DoublePoint, Double)
Subtraction operator - subtracts scalar from the specified point. ToString
Get string representation of the class.
(Overrides ValueTypeToString.)
Top Operators
NameDescription  Addition(DoublePoint, DoublePoint)  Addition(DoublePoint, Double)  Division
Division operator - divides coordinates of the specified point by scalar value.  Equality
Equality operator - checks if two points have equal coordinates.  (DoublePoint to IntPoint)
Explicit conversion to IntPoint.  (DoublePoint to Point)
Explicit conversion to Point.  Inequality
Inequality operator - checks if two points have different coordinates.  Multiply
Multiplication operator - multiplies coordinates of the specified point by scalar value.  Subtraction(DoublePoint, DoublePoint)
Subtraction operator - subtracts values of two points.  Subtraction(DoublePoint, Double)
Subtraction operator - subtracts scalar from the specified point.
Top Fields
NameDescription X
X coordinate. Y
Y coordinate.
Top Extension Methods
NameDescription HasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) IsEqual
Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices.
(Defined by Matrix.) To(Type)Overloaded.
Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) ToTOverloaded.
Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.)
Top Remarks

The structure is used to store a pair of floating point coordinates with double precision.

Sample usage:

```// assigning coordinates in the constructor
DoublePoint p1 = new DoublePoint( 10, 20 );
// creating a point and assigning coordinates later
DoublePoint p2;
p2.X = 30;
p2.Y = 40;
// calculating distance between two points
double distance = p1.DistanceTo( p2 );``` See Also
