According to php.net, the largest possible float is ~1.8e308.
wikipedia.org offers more insight, suggesting that is, exactly,
0x7FEFFFFFFFFFFFFF. This sorta begs the question... how can this
number be represented in PHP without resorting to the decimal notation?

<?
echo 0x7FEFFFFFFFFFFFFF;
?>

....doesn't work. Nor does...

<?
echo hexdec('7FEFFFFFFFFFFFFF');
?>

So... any ideas as to what will work?
