Returns the integer index of an ordinal value.
Declaration
| Value | [in] | Required | Variant | |
| Result | Integer |
Description
Ordinal data types consist of a set of countable ordered values. That is, ordinal values can be counted one by one in a specific order and therefore each value has the corresponding integer index. Typical examples of ordinal values are integer numbers, characters and Boolean values.
The Ord function returns the index of the specified ordinal value. For instance, it can be used to get ASCII codes of characters.
Parameters
The function has one parameter:
Value
The ordinal value whose numeric index you want to get.
Return Value
An integer number that specifies the ordinal index of the Value:
-
If Value is an integer number, the function returns this value.
-
If Value is a string, the function returns the ASCII code of the first character in this string.
-
If Value is a Boolean, the function returns 1 if it is True, and 0 if it is False.
If Value is not of the ordinal type (for example, if it is a floating-point value), the function returns 0.
Example
The following example illustrates the Ord function result for various ordinal values.
DelphiScript
procedure Test;
begin
Log.Message( Ord(123) ); // 123
Log.Message( Ord(-42) ); // -42
Log.Message( Ord('A') ); // 65
Log.Message( Ord(' ') ); // 32
Log.Message( Ord(true) ); // 1
Log.Message( Ord(false) ); // 0
end;
