Synopsis

This class is a specialization of the abstract base class DataConversion. It contains functions to convert data from/to the canonical format using the static functions in class CanonicalConversion.

Example

See example in class DataConversion.

Motivation

This class is an addition to CanonicalConversion to be able to use the conversion functions in a polymorphic way.

To Do

Support data type long double.
