Number question

[Craig Keightley]

Is there a way to "round" (bad use of the word) a number to the nearest 5
eg
4 => 5
7 => 10
1 => 5
12 => 15

Many Thanks for any help provide
Craig

$round_x = 5 * ceil($x/5);

or (*maybe* faster):
$round_x = $x + ((5 - ($x%5)) % 5);

function round5($val) {

$div=floor((int)$val/(int)5);
if($val%5) {
$div++;
}

return $div * 5;
}

Try this sample:

for($x=0;$x<30;$x++)
{
if( !($x % 5) ) // if mod is zero, we're already there
{
$nearest = $x;
}
else
{
$nearest = (intval($x/5)+1)*5;
}

echo "\n $x rounds to $nearest";
}

Or as a function:

function another_round5($x)
{
if( !($x % 5) )
return($x);
else
return((intval($x/5)+1)*5);
}

Thanks all but i went with this:
$round_x = 5 * ceil($x/5);

Your code gives 10 as output for 6 input, where nearest 5
should be 6.

Try this:

$round_x = 5 * round( $x / 5 );

Sure:

$oldnumber = 12;
$newnumber = ceil($oldnumber / 5) * 5; // $newnumber = 15...

Cheers,

Thats what i want it to do:
Round Up
e.g 6 <= 10
therefore 6 == 10
