## Definition

template<typename Point_2, typename Creator>
class CGAL::Random_points_on_circle_2< Point_2, Creator >

The class `Random_points_on_circle_2` is an input iterator creating points uniformly distributed on a circle.

The default `Creator` is `Creator_uniform_2<Kernel_traits<Point_2>::Kernel::RT,Point_2>`. The generated points are computed using floating point arithmetic, whatever the Kernel is, thus they are on the circle/sphere only up to rounding errors.

Is model of
  `InputIterator`
  `PointGenerator`

## Constructor & Destructor Documentation

## ◆ Random_points_on_circle_2()

template<typename Point_2 , typename Creator >

CGAL::Random_points_on_circle_2< Point_2, Creator >::Random_points_on_circle_2 | ( | double | r = `1.0`,
|  | Random & | rnd = `get_default_random()`
| ) |  |

creates an input iterator `g` generating points of type `Point_2` uniformly distributed on the circle with radius \( r\), i.e. \( |*g| == r\).

A single random number is needed from `rnd` for each point.
