## ◆ Compute_approximate_hyperbolic_diameter

typedef unspecified_type Periodic_4HyperbolicDelaunayTriangulationTraits_2::Compute_approximate_hyperbolic_diameter

Must provide the function operator.

`double operator()(Hyperbolic_point_2 p1, Hyperbolic_point_2 p2, Hyperbolic_point_2 p3),`

which returns a floating-point approximation of the hyperbolic diameter of the circle defined by the points `p1, p2,` and `p3`.
