Exact equality
bool operator!=(const ROOT::Math::Polar3D<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();}
T y()
{ return Y();}
T z()
{ return Z(); }
void SetX(ROOT::Math::Polar3D<double>::Scalar x)
 ============= Specializations for improved speed ==================
 (none)
 ====== Set member functions for coordinates in other systems =======
