43// <synopsis>
44// Templated functions to convert scalars from one type to another.
45// They are useful to be able to convert a DComplex to a Complex
46// in templated classes.
47// A Complex,DComplex specialisation is necessary because the complex
48// class in the standard C++ library does not have such an automatic
49// conversion.
