I’ve been trying to come up with a solution to a little PHP round() problem I’m having.

I’m trying to add tax to a subtotal…pretty simple:

```php

$tax= round(($subTotal*.0825),2);

```

Most of the time this works fine, however, on the rare occasion that the tax comes back as a whole dollar or whole 10 cents, it drops the extra 0’s at the end.

Is there a way to check if that has happened and add the necessary 0’s (1 or 2) to the end of the string if needed?

Thanks for the help guys!!!
