decimal points

Manat

I have a poll going on on my intranet.
all votes are stored in a data file.

However there is a decimal point on the voting percentage.
Would anyone know how to round it off to exclude decimal points?

do{
$subdata=explode("][",$data[$a]);
$votes += $subdata[2];
$a++;
}while($a < $nb_answers);
$a=1;
$b="answerv";
$v=100/$votes;
echo "<tr><td>$data[0] ";

do{
$subdata=explode("][",$data[$a]);
$av = $subdata[2] * $v;
echo "$subdata[0] -"; printf(" %01.1f", $av); echo"% ";
$p2v = 100-$av;
echo "<img src=\"$subdata[1]\" width=\"$av\" height=\"10\"><img src=\"$image\" width=\"$p2v\" height=\"10\"> ";
$a++;
} while ($a < $nb_answers);

}

You will want to look into using the [man]round()[/man] function.

OK,

so I did this:

$av = round($subdata[2] * $v);

So it works, but there is still a decimal point.
It rounds it off, but shows at 45.0%
how do I take out the .o?

thanks

rgermain

Try something like:

<?
 $av = round($subdata[2] * $v,0); 
?>

Hi,

No it didn't work, It didn't generate an error, but the decimal point is still there.

I was just looking through your code and I noticed that you are using printf. There could be the problem. I normally don't deal with printf that much, but I think by using printf(" %01.1f", $av); you are telling it format with 1 floating point decimal. Look in to [man]printf[/man]

I would just remove the printf all together and see if that helps.
