`#include <CGAL/point_generators_2.h>`

## Definition

template<typename Point_2, typename Creator>
class CGAL::Random_points_in_square_2< Point_2, Creator >

The class `Random_points_in_square_2` is an input iterator creating points uniformly distributed in a half-open square.

The default `Creator` is `Creator_uniform_2<Kernel_traits<Point_2>::Kernel::RT,Point_2>`.

Is model of
  `InputIterator`
  `PointGenerator`

| Random_points_in_square_2 (double a, Random &rnd=get_default_random())
| Creates an input iterator `g` generating points of type `Point_2` uniformly distributed in the half-open square with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g: -a \le p.x() < a\) and \( -a \le p.y() < a\).

## Constructor & Destructor Documentation

## ◆ Random_points_in_square_2()

template<typename Point_2 , typename Creator >

CGAL::Random_points_in_square_2< Point_2, Creator >::Random_points_in_square_2 | ( | double | a,
|  | Random & | rnd = `get_default_random()`
| ) |  |

Creates an input iterator `g` generating points of type `Point_2` uniformly distributed in the half-open square with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g: -a \le p.x() < a\) and \( -a \le p.y() < a\).

Two random numbers are needed from `rnd` for each point.
