template<typename T >
using	IsReal = std::enable_if_t< std::is_floating_point< T >::value, bool >
template<typename T >
using	RealAlias = typename RealAlias_impl< T >::value_type
	If you have a function templated on a value that can be real or complex and you need to get the base Real type if its complex or just the real. More...
template<typename TREAL , typename TREF , typename = std::enable_if_t<std::is_floating_point<TREAL>::value>>
using	ValueAlias = typename ValueAlias_impl< TREAL, TREF >::value_type
	If you need to make a value type of a given precision based on a reference value type set the desired POD float point type as TREAL and set the reference type as TREF. More...

Functions
float	real (const float &c)
	real part of a scalar. Cannot be replaced by std::real due to AFQMC specific needs. More...
double	real (const double &c)
float	real (const std::complex< float > &c)
double	real (const std::complex< double > &c)
float	imag (const float &c)
	imaginary part of a scalar. Cannot be replaced by std::imag due to AFQMC specific needs. More...
double	imag (const double &c)
float	imag (const std::complex< float > &c)
double	imag (const std::complex< double > &c)
float	conj (const float &c)
	Workaround to allow conj on scalar to return real instead of complex. More...
double	conj (const double &c)
std::complex< float >	conj (const std::complex< float > &c)
std::complex< double >	conj (const std::complex< double > &c)

void	copy_with_complex_cast (const std::complex< double > &source, double &dest)
