Facorial Calculator

[acskurucz]

Code: Select all

<?php
$factorial="1";
$n=1000;
for($i=1; $i<=$n; ++$i) $factorial=bcmul($factorial, $i);

echo $factorial;
?>

It can handle very very very big numbers.

I turned your code into a function:

function factorial($x){
$factorial="1";
for($i=1; $i<=$x; ++$i) $factorial=bcmul($factorial, $i);
return $factorial;
}


P.S. I incorporated that function into my bot

hehe,
