This function lets you round any number to the nearest last ending digit(s).
| <?php
function Round_Nearest($number, $nearest, $type = null)
{
$negative = false;
if ($number[0] == '-')
{
$negative = true;
}
$number = abs(intval($number));
$nearest = abs(intval($nearest));
if ($number <= $nearest)
{
$result = $nearest;
}
else
{
$ceil = $nearest - substr($number, strlen($number) - strlen($nearest));
$floor = $nearest - substr($number, strlen($number) - strlen($nearest)) - pow(10, strlen($nearest));
switch ($type)
{
case 'ceil':
$result = $number + $ceil;
break;
case 'floor':
$result = $number + $floor;
break;
default:
$result = $number + ((abs($ceil) <= abs($floor)) ? $ceil : $floor);
break;
}
}
if ($negative === true)
{
$result = '-' . $result;
}
return $result;
}
