Hi friends,

Please try following PHP code:

<? 
$a=unpack("dx",pack("d",3.1415926));
print($a["x"]);
?>

It's supposed to be "3.1415926", but it return "6.3886672646707E-315".

It seems the problem appears in all versions of PHP4, includes PHP 4.0, PHP 4.0.1, PHP 4.0.1 pl2 and PHP 4.0.2, under Windows 98 environment.


Thanks & Regards,
Edward Zhang
