Add a precision to your value and object > Thanks for the reply Thomas. I appreciate it. Could you explain what you mean by adding a precision? I have tried pass the $round var to the convertTo method and the toString method, but it seems to have no effect. Thanks again. I'll probably look at using the trunk release, but am interested in what you mean by adding a precision. Thanks again! > 2.) Use trunk release (a workaround has been added some weeks ago) > 3.)
