{
  // For G4PhysicsLogVector, FindBinLocation is implemented using
  // a simple arithmetic calculation.
  //
  // Because this is a virtual function, it is accessed through a
  // pointer to the G4PhyiscsVector object for most usages. In this
  // case, 'inline' will not be invoked. However, there is a possibility 
  // that the user access to the G4PhysicsLogVector object directly and 
  // not through pointers or references. In this case, the 'inline' will
  // be invoked. (See R.B.Murray, "C++ Strategies and Tactics", Chap.6.6)
  //G4cout << "G4PhysicsLogVector::FindBinLocation: e= " << theEnergy
