## CGAL::orientation

#include <CGAL/predicates_d.h>

template <class ForwardIterator>
Orientation |
orientation ( | ForwardIterator first, ForwardIterator last)
|  | determines the orientation of the points of the tuple A = tuple [first,last) where A consists of d+1 points in d-space. This is the sign of the determinant |
1 | 1 | 1 | 1
A[0] | A[1] | ... | A[d]
| where A[i] denotes the Cartesian coordinate vector of the i-th point in A. Precondition: size [first,last) == d+1 and A[i].dimension() == d 0 i d. Requirement: The value type of ForwardIterator is Point_d<R>.
