Polar2D & operator=(const ROOT::Math::Polar2D<double>& v)

      assignment operator

void SetCoordinates(ROOT::Math::Polar2D<double>::Scalar r, ROOT::Math::Polar2D<double>::Scalar phi)

      Set internal data based on 2 Scalar numbers

{ fR=r; fPhi=phi; Restrict(); }

void GetCoordinates(ROOT::Math::Polar2D<double>::Scalar& r, ROOT::Math::Polar2D<double>::Scalar& phi) const

      get internal data into 2 Scalar numbers

{r=fR; phi=fPhi;}

Scalar Phi()

{ return fPhi; }

Scalar X()

{ return fR*std::cos(fPhi);}

Scalar Y()

{ return fR*std::sin(fPhi);}

Scalar Mag2()

{ return fR*fR;}

void SetR(const double& r)

 setters (only for data members)

       set the r coordinate value keeping phi constant

void SetPhi(const double& phi)

       set the phi coordinate value keeping r constant

void SetXY(ROOT::Math::Polar2D<double>::Scalar a, ROOT::Math::Polar2D<double>::Scalar b)

       set all values using cartesian coordinates

double pi()

{ return M_PI; }

void Scale(double a)

       scale by a scalar quantity - for polar coordinates r changes

void Rotate(double angle)

      rotate the vector

bool operator==(const ROOT::Math::Polar2D<double>& rhs) const

      Exact equality

bool operator!=(const ROOT::Math::Polar2D<double>& rhs) const

{return !(operator==(rhs));}

T x()

 ============= Compatibility section ==================
 The following make this coordinate system look enough like a CLHEP
 vector that an assignment member template can work with either

{ return X();}

void SetX(ROOT::Math::Polar2D<double>::Scalar a)

 ============= Specializations for improved speed ==================
 (none)
 ====== Set member functions for coordinates in other systems =======
