Byte and Integer

[Skrim 11]

Delphi 10.4

 

procedure TForm1.Button1Click(Sender: TObject);
var
  i : byte;
  j : integer;
begin

  screen.Cursor:=crHourGlass;

  try

    j:=30000;

    i:=j;

    showmessage(inttostr(i));

  finally

    screen.Cursor:=crDefault;

  end;

end;

 

If I set i=3 then inttostr gives me 3

If I set i=3000 then inttostr gives me 184

If I set i=30000 then inttostr gives me 48

 

I thought 3000 and 30000 would raise an exception, as they are out of range?

You should enable both range checking and overflow checking. Then you'll see your exceptions.

Thanks, I thought they were set by default.
Moral, don't take anything for granted 🙂

They should be, don't know why Emba doesn't do this

Couldn't take the traffic of tens of devs trying to vote for range checking enabled by default

Did my civic duty and helped push the server out of the mud.* Then voted for the issue.

I guess it's rather a missing overflow check in the server software for the vote counter 😉
But I guess this Jira software is not written in Delphi (oh, if it were overflow checking would be available and this issue would have been caught during testing...)

 

Of course I voted for this as well.
