This is called out explicitly at the documentation for enumerated types:

Several predefined functions operate on ordinal values and type identifiers. The most important of them are summarized below.

| Function |                       Parameter                       |                      Return value | Remarks                                           |
|----------|:-----------------------------------------------------:|----------------------------------:|---------------------------------------------------|
| Ord      |                   Ordinal expression                  |  Ordinality of expression's value | Does not take Int64 arguments.                    |
| Pred     |                   Ordinal expression                  | Predecessor of expression's value |                                                   |
| Succ     |                   Ordinal expression                  |   Successor of expression's value |                                                   |
| High     | Ordinal type identifier or   variable of ordinal type | Highest value in type             | Also operates on short-string   types and arrays. |
| Low      | Ordinal type identifier or   variable of ordinal type | Lowest value in type              | Also operates on short-string   types and arrays. |
