Detailed Description

template<typename number>
struct numbers::NumberTraits< std::complex< number > >

Specialization of the general NumberTraits class that provides the relevant information if the underlying data type is std::complex<T>.

Member Typedef Documentation

template<typename number >
typedef number numbers::NumberTraits< std::complex< number > >::real_type

For this data type, typedef the corresponding real type. Since this specialization of the template is selected for number types std::complex<T>, the real type is equal to the type used to store the two components of the complex number.

Member Function Documentation

template<typename number >
std::complex< number > numbers::NumberTraits< std::complex< number > >::conjugate ( const std::complex< number > &  x ) [static]

Return the complex-conjugate of the given number.

Definition at line 337 of file numbers.h.

template<typename number >
NumberTraits< std::complex< number > >::real_type numbers::NumberTraits< std::complex< number > >::abs_square ( const std::complex< number > &  x ) [static]

Return the square of the absolute value of the given number. Since this specialization of the general template is chosen for types equal to std::complex, this function returns the product of a number and its complex conjugate.

Definition at line 355 of file numbers.h.

template<typename number >
NumberTraits< std::complex< number > >::real_type numbers::NumberTraits< std::complex< number > >::abs ( const std::complex< number > &  x ) [static]

Return the absolute value of a complex number.

Definition at line 346 of file numbers.h.


Member Data Documentation

template<typename number >
const bool numbers::NumberTraits< std::complex< number > >::is_complex = true [static]

A flag that specifies whether the template type given to this class is complex or real. Since this specialization of the general template is selected for complex types, the answer is true.
