function Distance(const X1, Y1, X2, Y2: Integer): Extended;

Source Code

function MyDistance(const X1, Y1, X2, Y2: Integer): Extended;
var
  A, B: Extended;
begin
  A := X1 - X2;
  B := Y1 - Y2;
  Result := Sqrt(A * A + B * B);
end;

• Before 3.21 the workaround for larger distances was not yet implemented.
• Bedore 3.37 returned an integer value
