Algorithms and Utility Functions [Point] Detailed Description Algorithms and Utility Functions for points. Example: assert(iround(point2<double>(3.1, 3.9)) == point2<int>(3,4)); Functions point2< int >  boost::gil::iround (const point2< float > &p) point2< int >  boost::gil::iround (const point2< double > &p) point2< int >  boost::gil::ifloor (const point2< float > &p) point2< int >  boost::gil::ifloor (const point2< double > &p) point2< int >  boost::gil::iceil (const point2< float > &p) point2< int >  boost::gil::iceil (const point2< double > &p)
