  double d0 = CGAL::to_double(point.x());


A note about the use of mails: next time, please open a *new* discussion 
thread. The Reply button of your email software is only to *continue* a 
discussion, even if you change the subject. Next time perhaps you will not 
get 
answers because people able to answer you will not see you email lost deep in 
another discussion thread.
