 Geom2d_Direction (const Standard_Real X, const Standard_Real Y)
 Creates a unit vector with it 2 cartesian coordinates.
Raised if Sqrt( X*X + Y*Y) <= Resolution from gp.

 Geom2d_Direction (const gp_Dir2d &V)
 Creates a persistent copy of <me>.

void SetCoord (const Standard_Real X, const Standard_Real Y)
 Assigns the coordinates X and Y to this unit vector,
then normalizes it.
Exceptions
Standard_ConstructionError if Sqrt(X*X +
Y*Y) is less than or equal to gp::Resolution().

void SetDir2d (const gp_Dir2d &V)
 Converts the gp_Dir2d unit vector V into this unit vector.

void SetX (const Standard_Real X)
 Assigns a value to the X coordinate of this unit vector, then normalizes it.
Exceptions
Standard_ConstructionError if the value assigned
causes the magnitude of the vector to become less
than or equal to gp::Resolution().

void SetY (const Standard_Real Y)
 Assigns a value to the Y coordinate of this unit vector, then normalizes it.
Exceptions
Standard_ConstructionError if the value assigned
causes the magnitude of the vector to become less
than or equal to gp::Resolution().

gp_Dir2d Dir2d () const
 Converts this unit vector into a gp_Dir2d unit vector.

Standard_Real Magnitude () const
 returns 1.0

Standard_Real SquareMagnitude () const
 returns 1.0

Standard_Real Crossed (const Handle< Geom2d_Vector > &Other) const
 Computes the cross product between <me> and <Other>.

Standard_Real operator^ (const Handle< Geom2d_Vector > &Other) const
void Transform (const gp_Trsf2d &T)
 Applies the transformation T to this unit vector, then normalizes it.

Handle_Geom2d_Geometry Copy () const
 Creates a new object which is a copy of this unit vector.
