Recall that Eigen allows - * only the following types for \a T: \c int, \c float, \c double, - * \c std::complex<float>, \c std::complex<double>, and \c long \c double (especially - * useful to enforce x87 arithmetics when SSE is the default). - * - * The provided data consists of: - * \li A typedef \a Real, giving the "real part" type of \a T. If \a T is already real, - * then \a Real is just a typedef to \a T. If \a T is \c std::complex<U> then \a Real - * is a typedef to \a U. - * \li A typedef \a FloatingPoint, giving the "floating-point type" of \a T. If \a T is - * \c int, then \a FloatingPoint is a typedef to \c double. Otherwise, \a FloatingPoint - * is a typedef to \a T. - * \li An enum value \a IsComplex. It is equal to 1 if \a T is a \c std::complex - * type, and to 0 otherwise. - * \li An enum \a HasFloatingPoint. It is equal to \c 0 if \a T is \c int, - * and to \c 1 otherwise. - */ -template<typename T> struct NumTraits; - -template<> struct NumTraits<int> -{ - typedef int Real; - typedef double FloatingPoint; - enum { - IsComplex = 0, - HasFloatingPoint = 0, - ReadCost = 1, - AddCost = 1, - MulCost = 1 - }; -}; - -template<> struct NumTraits<float> -{ - typedef float Real; - typedef float FloatingPoint; - enum { - IsComplex = 0, - HasFloatingPoint = 1, - ReadCost = 1, - AddCost = 1, - MulCost = 1 - }; -}; - -template<> struct NumTraits<double> -{ - typedef double Real; - typedef double FloatingPoint; - enum { - IsComplex = 0, - HasFloatingPoint = 1, - ReadCost = 1, - AddCost = 1, - MulCost = 1 - }; -}; - -template<typename _Real> struct NumTraits<std::complex<_Real> > -{ - typedef _Real Real; - typedef std::complex<_Real> FloatingPoint; - enum { - IsComplex = 1, - HasFloatingPoint = NumTraits<Real>::HasFloatingPoint, - ReadCost = 2, - AddCost = 2 * NumTraits<Real>::AddCost, - MulCost = 4 * NumTraits<Real>::MulCost + 2 * NumTraits<Real>::AddCost - }; -}; - -template<> struct NumTraits<long long int> -{ - typedef long long int Real; - typedef long double FloatingPoint; - enum { - IsComplex = 0, - HasFloatingPoint = 0, - ReadCost = 1, - AddCost = 1, - MulCost = 1 - }; -}; - -template<> struct NumTraits<long double> -{ - typedef long double Real; - typedef long double FloatingPoint; - enum { - IsComplex = 0, - HasFloatingPoint = 1, - ReadCost = 1, - AddCost = 1, - MulCost = 1 - }; -}; - -template<> struct NumTraits<bool> -{ - typedef bool Real; - typedef float FloatingPoint; - enum { - IsComplex = 0, - HasFloatingPoint = 0, - ReadCost = 1, - AddCost = 1, - MulCost = 1 - }; -}; - -#endif // EIGEN_NUMTRAITS_H |
