Bug description: 64 bit integer support
There is some kind of 64 bit integers support, isn't it? I tried this code on several
machines running on windows and linux platforms, and it produces the same results:
ex. 1:
for ($i=0; $i < 64; $i++)
echo "<br>$i - " . (1 << $i);
doing just fine with 31 bit, so $i must be 32 signed integer, but...
ex. 2:
for ($j=1, $i=0; $i < 64; $i++, $j*=2)
echo "<br>$i - $j";
seems to work fine until $j is less than 15 digits long (2^47), for example you may
add echo $j % 10 and it would display -8 for each $i >= 47. But, then again...
ex. 3:
$arr = str_pad("1", 64, "0");
$y = mysql_fetch_object(mysql_query("SELECT CONV('$arr', 2, 10) AS xx"));
echo $y->xx;
works just fine, as the $y->xx is unsigned 64 bit integer? But I must admit, this is a
silly workaround...
