#### strategy::distance::pythagoras_box_box

Strategy to calculate the distance between two boxes.

###### Synopsis

    template<typename CalculationType>
    class strategy::distance::pythagoras_box_box
    {
      // ...
    };

###### Template parameter(s)

Parameter | Default | Description
--- | --- | ---
typename CalculationType | void | numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point

###### Member Function(s)

Function | Description | Parameters | Returns
--- | --- | --- | ---

    template<typename Box1, typename Box2>
    calculation_type< Box1, Box2 >::type apply(Box1 const & box1, Box2 const & box2)

applies the distance calculation using pythagoras_box_box

Box1 const &: box1: first box

Box2 const &: box2: second box

the calculated distance (including taking the square root)
