// <synopsis>
// This class is a specialization of the abstract base class
// <linkto class=DataConversion>DataConversion</linkto>.
// It contains functions to convert data from/to the canonical format
// using the static functions in class <linkto class=CanonicalConversion>
// CanonicalConversion</linkto>.
// </synopsis>
// <example>
// See example in class <linkto class=DataConversion>DataConversion</linkto>.
// </example>
// <motivation>
// This class is an addition to <linkto class=CanonicalConversion>
// CanonicalConversion</linkto>
// to be able to use the conversion functions in a polymorphic way.
// </motivation>
// <todo asof="$DATE$">
// <li> Support data type long double.
