NAN when dividing 0 by 0

BvstedCrew

I made a Poll Voting with an Result Page. But wenn there are no votes it gives me an NAN Calc Error.

Code:

<div class="progress-bar" style="background-color: #38b673; width:<?= @(($poll_answer['votes'] / $total_votes) * 100)?>%">
<?= @round(($poll_answer['votes'] / $total_votes) * 100) ?>%
</div>

I tried different things, but nothing works.

Maybe anyone knows how to fix.

You can just use max() function to overcome divide by 0 issue.

<?php echo round(($poll_answer['votes'] / max(1,$total_votes)) * 100); ?>
