IceKarma said: "If you want, say, 2.6 to round to 3, and -2.6 to round to -3, you want round(),
which rounds away from zero."
That's not always true. round() doesn't work that way, like zomis2k said it just rounds up
_or_ down to the nearest non-decimal number. However this should work.
<?php
function roundaway($num) {
if ($num > 0)
return ceil($num);
elseif ($num < 0)
return floor($num);
elseif ($num == 0)
return 0;
}
?>
