Function documentation

Polar2D & operator=(const ROOT::Math::Polar2D<Double32_t>& v)
assignment operator
void SetCoordinates(ROOT::Math::Polar2D<Double32_t>::Scalar r, ROOT::Math::Polar2D<Double32_t>::Scalar phi)
Set internal data based on 2 Scalar numbers
{ fR=r; fPhi=phi; Restrict(); }
void GetCoordinates(ROOT::Math::Polar2D<Double32_t>::Scalar& r, ROOT::Math::Polar2D<Double32_t>::Scalar& phi) const
get internal data into 2 Scalar numbers
{r=fR; phi=fPhi;}
Scalar R()
{ return fR;}
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 Double32_t& r)
 setters (only for data members)

set the r coordinate value keeping phi constant
void SetPhi(const Double32_t& phi)
set the phi coordinate value keeping r constant
Restrict()
void SetXY(ROOT::Math::Polar2D<Double32_t>::Scalar x, ROOT::Math::Polar2D<Double32_t>::Scalar y)
 all values using cartesian coordina
double pi()
{ return M_PI; }
void Scale(Double32_t a)
cale by a scalar quantity - for polar coordinates r change
Negate()
void Rotate(Double32_t angle)
ate the vec
bool operator==(const ROOT::Math::Polar2D<Double32_t>& rhs) const
Exact equality
bool operator!=(const ROOT::Math::Polar2D<Double32_t>& 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();}
T y()
{ return Y();}
void SetX(ROOT::Math::Polar2D<Double32_t>::Scalar x)
 ============= Specializations for improved speed ==================
 (none)
 ====== Set member functions for coordinates in other systems =======
void SetY(ROOT::Math::Polar2D<Double32_t>::Scalar y)
