The Vector2d type exposes the following members.

Constructors

	Name	Description
	Vector2d	Initializes a new instance of the vector based on two, X and Y, components.

Properties

	Name	Description
	IsValid	Gets a value indicating whether this vector is valid. A valid vector must be formed of valid component values for x, y and z.
	Length	Computes the length (or magnitude, or size) of this vector. This is an application of Pythagoras' theorem.
	SquareLength	Returns the square of the length of the vector.
	Unset	Gets the value of the vector with components set as RhinoMath.UnsetValue,RhinoMath.UnsetValue.
	X	Gets or sets the X (first) component of this vector.
	Y	Gets or sets the Y (second) component of this vector.
	Zero	Gets the value of the vector with components 0,0.

Methods

	Name	Description
	Add	Sums up two vectors. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	CompareTo	Compares this Vector2d with another Vector2d. Components evaluation priority is first X, then Y.
	Divide	Divides a Vector2d by a number, having the effect of shrinking it. (Provided for languages that do not support operator overloading. You can use the / operator otherwise)
	EpsilonEquals	Check that all values in other are within epsilon of the values in this
	Equals(Object)	Determines whether the specified System.Object is a Vector2d and has the same value as the present vector. (Overrides ValueTypeEquals(Object).)
	Equals(Vector2d)	Determines whether the specified vector has the same value as the present vector.
	GetHashCode	Provides a hashing value for the present vector. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsTiny	Uses RhinoMath.ZeroTolerance for IsTiny calculation.
	IsTiny(Double)	Determines whether a vector is very short.
	Multiply(Double, Vector2d)	Multiplies a vector by a number, having the effect of scaling it. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Vector2d, Vector2d)	Multiplies two vectors together, returning the dot product (or inner product). (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Vector2d, Double)	Multiplies a vector by a number, having the effect of scaling it. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Negate	Computes the reversed vector. (Provided for languages that do not support operator overloading. You can use the - unary operator otherwise)
	Rotate	Rotates this vector.
	Subtract	Subtracts the second vector from the first one. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	ToString	Constructs a string representation of the current vector. (Overrides ValueTypeToString.)
	ToString(String, IFormatProvider)	Formats the value of the current instance using the specified format.
	Unitize	Unitizes the vector in place. A unit vector has length 1 unit. An invalid or zero length vector cannot be unitized.

Operators

	Name	Description
	Addition	Sums up two vectors.
	Division	Divides a Vector2d by a number, having the effect of shrinking it.
	Equality	Determines whether two vectors have equal values.
	GreaterThan	Determines whether the first specified vector comes after (has superior sorting value than) the second vector. Components have decreasing evaluation priority: first X, then Y.
	GreaterThanOrEqual	Determines whether the first specified vector comes after (has superior sorting value than) the second vector, or it is equal to it. Components have decreasing evaluation priority: first X, then Y.
	Inequality	Determines whether two vectors have different values.
	LessThan	Determines whether the first specified vector comes before (has inferior sorting value than) the second vector. Components have decreasing evaluation priority: first X, then Y.
	LessThanOrEqual	Determines whether the first specified vector comes before (has inferior sorting value than) the second vector, or it is equal to it. Components have decreasing evaluation priority: first X, then Y.
	Multiply(Double, Vector2d)	Multiplies a vector by a number, having the effect of scaling it.
	Multiply(Vector2d, Vector2d)	Multiplies two vectors together, returning the dot product (or inner product).
	Multiply(Vector2d, Double)	Multiplies a vector by a number, having the effect of scaling it.
	Subtraction	Subtracts the second vector from the first one.
	UnaryNegation	Computes the opposite vector.
