Kernel::FT CGAL::approximate_angle (const CGAL::Vector_3< Kernel > &u, const CGAL::Vector_3< Kernel > &v)
returns an approximation of the angle between u and v. More...

## ◆ approximate_angle() [1/2]

template<typename Kernel >
 Kernel::FT CGAL::approximate_angle ( const CGAL::Point_3< Kernel > & p, const CGAL::Point_3< Kernel > & q, const CGAL::Point_3< Kernel > & r )

#include <CGAL/Kernel/global_functions.h>

returns an approximation of the angle between p-q and r-q.

The angle is given in degrees.

Precondition
p != q and r != q.

## ◆ approximate_angle() [2/2]

template<typename Kernel >
 Kernel::FT CGAL::approximate_angle ( const CGAL::Vector_3< Kernel > & u, const CGAL::Vector_3< Kernel > & v )

#include <CGAL/Kernel/global_functions.h>

returns an approximation of the angle between u and v.

The angle is given in degrees.

Precondition
u and v are not equal to the null vector.
