note 51515 added to function.number-format

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 */ ?> ---- Manual Page -- http://www.php.net/manual/en/function.number-format.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51515 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51515&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51515&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51515&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51515&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51515&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51515&report=yes Search -- http://master.php.net/manage/user-notes.php
