[fpc-devel] VAL behavior

2010-03-23 Thread Dariusz Mazur 

Hi
  I found different behavior of VAL function under Delphi and FPC

var
  i,io : integer

begin
  val('9 ',ii,io);
  writeln(ii);
  writeln(io);
end;


Delphi set ii to 9, FPC set 0 (io is equal 2)
is this bug?

Don't assume the value of ii (since it's invalid), if io  0

   


I don't ask about it. Only if this difference is a bug.

No. IMO not.

FWIW, TP gives the same results as FPC. Nevertheless, as already pointed
out by others, you should not rely on returned values in case of an error.
