Detailed Description

Quick comparison of types that can be safely promoted and/or converted to each other.

The comparison operations provided by this structure perform no negative value checking, meaning it is not applicable to all types. Check the value of the USABLE enumerator to determine if it applies to the types in question.

This structure is not meant for general use.
