[RESOLVED] rounding numbers up to the nearest dividable by 4

[elemelas]

hi guys

any ideas how to round the number to the nearest number dividable by some other number ? ( 😉 ) so for example:

$number = 6;

if($number % 4 == 0) { echo("ok"); }
else { }

and here i want to round that number up to nearest dividable by 4, so in this case: 8.

any ideas appreciated

You could do it as a one-liner like so:

function nearestMultiple($num, $mult) {
  return (($num % $mult) < floor($mult / 2) ? ($num - ($num % $mult)) : ($num + ($mult - ($num % $mult))));
}

Note that the function only works for integers though it doesn't include any error checking to verify that this condition is satisfied.

fantastic, thanks brad !

You could also use

$rounded = 4*ceil($number/4); // to round up
$rounded = 4*round($number/4); // to round to the nearest
