    I need to round a number to two decimal places. Here's the code. What is the correct code to round to two decimal places?

    $ctr= round(($row['number_clicks']/$row['impression'])*100) . "%";
    PHP:
    Thanks!

    Sometimes number_format can be useful too. I use it to format currencies and percentages too.

    Good luck!
