// <summary>A DataConversion class to convert between Modcomp format.</summary>
// <use visibility=export>
// <reviewed reviewer="" date="yyyy/mm/dd" tests="" demos="">
// </reviewed>
// <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 Modcomp format
// using the static functions in class <linkto class=ModcompConversion>
// ModcompConversion</linkto>.
// </synopsis>
// <example>
// See example in class <linkto class=DataConversion>DataConversion</linkto>.
// </example>
// <motivation>
// This class is an addition to <linkto class=ModcompConversion>
// ModcompConversion</linkto>
// to be able to use the conversion functions in a polymorphic way.
// </motivation>
// <todo asof="$DATE$">
// <li> Support data type long Double.
