Explicit enumeration conversions

The explicit enumeration conversions are: From sbyte, byte, short, ushort, int, uint, long, ulong, char, float, double, or decimal to any enum-type. From any enum-type to sbyte, byte, short, ushort, int, uint, long, ulong, char, float, double, or decimal. From any enum-type to any other enum-type.
An explicit enumeration conversion between two types is processed by treating any participating enum-type as the underlying type of that enum-type, and then performing an implicit or explicit numeric conversion between the resulting types. [Example: For example, given an enum-type E with and underlying type of int, a conversion from E to byte is processed as an explicit numeric conversion (13.2.1) from int to byte, and a conversion from byte to E is processed as an implicit numeric conversion (13.1.2) from byte to int. end example]
