jb::extract_value_type

struct jb::extract_value_type

template<typename T>
struct jb::extract_value_type< T >

Generic function to extract the floating point type of std::complex.

Some of the algorithms and data structures in JayBeams need to work for both std::complex<> and for primitive floating point values such as 'float'. These functions sometimes need a generic way to extract the 'T' parameter in a std::complex<T>. This function can be used to perform such conversions, for example:

template<typename sample_t> class Foo {
  typedef typename jb::extra_value_type<sample_t>::precision prec;
  prec epsilon = std::numeric_limits<prec>::epsilon();
};

Such code would work whether sample_t is a std::complex<T> or a primitive floating point value.
