Rounding percentage value to a whole number in poll results

Currently, my results page in my polls list the percentage out to the nearest hundreth. I'd like to round it to a whole number.

Here is the code for the percentage in the Survey index file:

Code:

   if($sum) {
      $percent = 100 * $optionCount / $sum;
   } else {
      $percent = 0;

Can anyone help me add the necessary code to round that value?

There is also code that prints the value that might be the one to adjust:

Code:

printf(" %.2f%%", $percent);

Use the round() function Smile

Wow, fast reply!

I thought I'd tinker around with it a bit for a little trial and error and I think I might have found the fix.

I changed

Code:

printf(" %.2f%%", $percent);

to

Code:

printf(" %.0f%%", $percent);

It appears like it is working, as my results now are whole numbers Smile
