var
  float : extended;

begin
  // Set up our floating point number
  float := 1234.567;

  // Display a sample value using all of the format options

  // Round out the decimal value
  ShowMessage('##### : '+FormatFloat('#####', float));
  ShowMessage('00000 : '+FormatFloat('00000', float));
  ShowMessage('0    : '+FormatFloat('0'    , float));
  ShowMessage('#,##0 : '+FormatFloat('#,##0', float));
  ShowMessage(',0    : '+FormatFloat(',0'  , float));
  ShowMessage('');

  // Include the decimal value
  ShowMessage('0.#### : '+FormatFloat('0.####', float));
  ShowMessage('0.0000 : '+FormatFloat('0.0000', float));
  ShowMessage('');

  // Scientific format
  ShowMessage('0.0000000E+00 : '+FormatFloat('0.0000000E+00', float));
  ShowMessage('0.0000000E-00 : '+FormatFloat('0.0000000E-00', float));
  ShowMessage('#.#######E-## : '+FormatFloat('#.#######E-##', float));
  ShowMessage('');

  // Include freeform text
  ShowMessage('"Value = "0.0 : '+FormatFloat('"Value = "0.0', float));
  ShowMessage('');

  // Different formatting for negative numbers
  ShowMessage('0.0 : '+FormatFloat('0.0'              , -1234.567));
  ShowMessage('0.0 "CR";0.0 "DB" : '+
              FormatFloat('0.0 "CR";0.0 "DB"', -1234.567));
  ShowMessage('0.0 "CR";0.0 "DB" : '+
              FormatFloat('0.0 "CR";0.0 "DB"',  1234.567));
  ShowMessage('');

  // Different format for zero value
  ShowMessage('0.0 : '+FormatFloat('0.0' , 0.0));
  ShowMessage('0.0;-0.0;"Nothing" : '+
              FormatFloat('0.0;-0.0;"Nothing"', 0.0));
end;

og så den du nok skal bruge:

  ShowMessage(FormatFloat('0.##', float));
