Detailed Description

template<class T>
class itk::NumericTraits< T >

Define additional traits for native types such as int or float.

NumericTraits is used to extend the traits associated with native types such as float, char, int, and so on. These traits are extensions of the standard <numeric_limits> defined by the C++ compilers. Some of the added traits include minimum and maximum value; accumulation type; etc.
