SysUtilsFormat (Delphi)

Description

This example uses several edit boxes and a button on a form. After filling in input data into the edit boxes, press the Format button to display the resulting formatted string.

Code

procedure TForm1.Button1Click(Sender: TObject);
var
  signed_integer: Integer;
    hexa_integer: Integer;
  floating_point: Extended;
            text: String;

begin
  { Extract the data from the edit boxes. }
  text := Edit1.Text;
  signed_integer := StrToInt(Edit2.Text);
  hexa_integer := StrToInt(Edit3.Text);
  floating_point := StrToFloat(Edit4.Text);

  {
    Format the data using the following rules:
    * Only the first three characters of text are displayed.
    * Signed_integer is displayed as a signed integer
      with ten padding zeros.
    * Hexa_integer is displayed in hexadecimal with eight padding zeros.
    * Floating_point is displayed as a fixed point value,
      using a width of 10 and a precision of two digits.
  }
  Edit5.Text :=
    Format('%.3s, %.10d, $%.8x, %10.2f',
    [text, signed_integer, hexa_integer, floating_point]);
end;
