You need to convert a float or double to a string in pascal
You can use the Function FloatToStr wich takes a float parameter. You can use the DoubleToStr for converting a double.
Here a little example:
procedure TForm1.Button1Click(Sender: TObject);
var s : string;
var mydoubleD : double;
mydoubleD := 3.14152341234234;
s := FloatToStr( mydoubleD );
//you could as well use s in the ShowMessage :-)
ShowMessage('Your Double is: ' + FloatToStr(mydoubleD));
