Cast Enumeration Value to Integer in Delphi

Is it possible to cast/convert an Enumeration Value to an Integer in the Delphi Programming Language?

If yes, then how?

Solution

  • 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.
