Note Submitter: mike at phpeeb dot com ---- Since number_format returns a string, you must perform all mathmatical functions on the number before applying number_format: <? $total = 100; $total = number_format($total, 2); $shipping = 20.00; $grand_total = $total + $shipping; echo number_format($grand_total, 2); /* The above will return 21.00 because $total is now a string, and no longer an integer or float. Since a string will have a value of 1, the addition of the two will return 21 and not 120. */ $total = 100; $shipping = 20.00; $grand_total = $total + $shipping; echo number_format($grand_total, 2); /* This works, and will return 120.00 as intended */ ?>
