| Random_points_on_square_2 (double a, Random &rnd=get_default_random())
| creates an input iterator `g` generating points of type `Point_2` uniformly distributed on the boundary of the square with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g:\) one coordinate is either \( a\) or \( -a\) and for the other coordinate \( c\) holds \( -a \le c < a\).

## Constructor & Destructor Documentation

## ◆ Random_points_on_square_2()

template<typename Point_2 , typename Creator >

CGAL::Random_points_on_square_2< Point_2, Creator >::Random_points_on_square_2 | ( | double | a,
|  | Random & | rnd = `get_default_random()`
| ) |  |

creates an input iterator `g` generating points of type `Point_2` uniformly distributed on the boundary of the square with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g:\) one coordinate is either \( a\) or \( -a\) and for the other coordinate \( c\) holds \( -a \le c < a\).

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