Dear all,
Can someone add an is_complex<T>::value trait to type_traits.hpp
::boost::is_complex<T>::value
trait to type_traits.hpp
I have found myself having to do this frequently. It strikes me that for
templated scientific codes it is a common requirement.
Below is my implementation, please feel free to add it. I should probably
inform the maintainer as well, John Maddock but there is no obvious way of
contacting him via the boost site.
namespace boost {
/**
* @brief Default trait for determining if a type is complex at
* compile-time.
*
* If the supplied template parameter type is not a std::complex<>
* then this struct is instantiated and the ::value enum will be 0
* at compile time.
*
* See also boost::is_float and associated in
* boost/type_traits.hpp
*/
template <typename T>
struct is_complex : ::boost::mpl::false_{};
/**
* @brief Overloaded trait for std::complex<> to determine if a
* type is complex at compile-time.
*
* If the supplied type is std::complex<double> or similar this
* overloaded struct is instantiated and the ::value enum will be
* 1 at compile-time.
*
* See also boost::is_float and associated in
* boost/type_traits.hpp
