Hi,
> ...
A little modification:
<?php
/**
* Rounds down to the nearest 50
*/
function myRound($val)
{
$units = intval(substr($val, -2));
return intval(substr($val, 0, -2) . ($units >= 50 ? '50' : '00'));
}
echo myRound(449) . '<br />'; // 400
echo myRound(450) . '<br />'; // 450
echo myRound(356) . '<br />'; // 350
echo myRound(79) . '<br />'; // 50
?>
PS I haven't checked if there's a PHP function for this.
