Strategy to calculate the distance between two points.
template<typename CalculationType> class strategy::distance::pythagoras { // ... };
| 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 | 
| Function | Description | Parameters | Returns | 
|---|---|---|---|
| 
 template<typename P1, typename P2> calculation_type< P1, P2 >::type apply(P1 const & p1, P2 const & p2) 
 | applies the distance calculation using pythagoras | P1 const &: p1: first point P2 const &: p2: second point | the calculated distance (including taking the square root) |
