Very Long Numbers

[Anon]

<?

$x = 0;
for ($i = 1; $i <= 63; $i++) {
$x = ($x + pow(2 , $i));
print $i . " - " . $x . "<br>";
}
?>

with this code i calculate a very big number like this...
63 - 1.844674407371E+019
but i want that as a real number... anybody knows how to ?

printf('%d - %f <br>', $i, $x);

that will format the output for you. Check the manual for more info.

You may have top look at the maximum precision defined in the php.ini.
Check the manual for more info on how many decimals PHP uses max.
