template<> struct NormTraits<ArithmeticType>

Unary traits for the calculation of the norm and squared norm of arithmetic objects.

#include <vigra/numerictraits.hxx>

This traits class is used to determine appropriate result types for the functions norm() and squaredNorm(). These functions are always declared like this (where ArithmeticType is a type that supports a norm):

NormTraits<ArithmeticType>::NormType norm(ArithmeticType const & t);
NormTraits<ArithmeticType>::SquaredNormType squaredNorm(ArithmeticType const & t);

The following members are defined in NormTraits<ArithmeticType>:

typedef ArithmeticType Type; | the type itself
typedef ... SquaredNormType; | result of squaredNorm(ArithmeticType)
typedef ... NormType; | result of norm(ArithmeticType) Usually equal to SquareRootTraits<SquaredNormType>::SquareRootResult

NormTraits for the built-in types are defined in #include <vigra/numerictraits.hxx>
