Detailed Description
template<typename T>
struct DGtal::NumberTraits< T >
struct DGtal::NumberTraits< T >
Aim: The traits class for all models of Cinteger.
Description of template class 'NumberTraits'
Since CInteger describes the concept Integer, this class is used by models of CIinteger to specialize some definitions related to Integer. For instance it defines whether a given Integer is signed or not and what is signed/unsigned version.
It inherits from NumberTraitsImpl by passing it the given number type without any CV qualifier.
