function DecToRoman(Decimal: Longint): string;
const
Numbers: array[1..13] of Integer =
(1, 4, 5, 9, 10, 40, 50, 90, 100,
400, 500, 900, 1000);
Romans: array[1..13] of string =
('I', 'IV', 'V', 'IX', 'X', 'XL',
'L', 'XC', 'C', 'CD', 'D', 'CM', 'M');
var
i: Integer;
begin
Result := '';
for i := 13 downto 1 do
while (Decimal >= Numbers[i]) do
begin
Decimal := Decimal - Numbers[i];
Result := Result + Romans[i];
end;
end;
//Example:
//Beispiel:
procedure TForm1.Button1Click(Sender: TObject);

label1.Caption := DecToRoman(5);
Label2.Caption := DecToRoman(458);
end;
