 This document looks at encapsulating data type conversions in new API functions on the !FdoDataValue class.
+
+
+=== API Changes ===
+
+Direct conversion from a source to a destination type will be supported by adding Create functions to each destination type, which take a value of the source type as a parameter.
+
+==== Main Functions ====
+
+The following functions will be added:
+
+
