class ROOT::Math::PositionVector2D<ROOT::Math::Cartesian2D<double>,ROOT::Math::DefaultCoordinateSystemTag>

Assignment from a foreign 2D vector type, for example, Hep2Vector
Precondition: v must implement methods x() and y()

Retrieve a copy of the coordinates object

Set internal data based on 2 Scalar numbers.
These are for example (x,y) for a cartesian vector or (r,phi) for a polar vector

get internal data into 2 Scalar numbers.
These are for example (x,y) for a cartesian vector or (r,phi) for a polar vector

 ------------------- Equality -----------------

Exact equality

 ------ Individual element access, in various coordinate systems ------

Cartesian X, converting if necessary from internal coordinate system.

Cartesian Y, converting if necessary from internal coordinate system.

Polar R, converting if necessary from internal coordinate system.

Polar phi, converting if necessary from internal coordinate system.

Magnitute squared ( r^2 in spherical coordinate)

 It is physically meaningless to speak of the unit vector corresponding
 to a point.
 ------ Setting individual elements present in coordinate system ------

Change X - Cartesian2D coordinates only

Change Y - Cartesian2D coordinates only

Change R - Polar2D coordinates only

Change Phi - Polar2D coordinates

Rotate by an angle
