Detailed Description

This file contains the class distanceType<T> which specifies three types that are recommended for the result of a distance calculation between two instances of T.

The three types are:

• distance_type is used when a simple distance is calculated between two instances of T which does not involve accumulation of squares or typical floating point operations.
• square_distance_type is used for the result of distances that involve the square of the type T.
• fp_distance_type is used for distances that involve floating point operations such as the sqrt or log functions.
