No, but it is easy to restrict a TEdit to only numbers.  Just put the 
following code into the TEdit's OnKeyPress handler:
procedure TForm1.Edit1KeyPress(Sender : TObject; var Key : Char);
const
    BACKSPACE = #8;
begin
    if not (Key in ['0'..'9', BACKSPACE]) then
        Key := #0;
end;
This handler can be shared among multiple TEdit controls on the same form.
