In Delphi code, Str converts X to a string representation according to the Width and Decimals formatting parameters. The effect is like a call to Write except the resulting string is stored in S instead of being written to a text file. 

X is an integer-type or real-type expression. Width and Decimals are integer-type expressions. S is a string-type variable or a zero-based character array variable if extended syntax is enabled.  

Delphi Examples: 

{
This example makes a simple string conversion routine
and then prints an integer to the screen.
}

function MakeItAString(I: Longint): string;
{ Convert any integer type to a string }
var
  S: string[11];
begin
  Str(I, S);
  Result:= S;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Canvas.TextOut(10, 10, MakeItAString(-5322));
end;
