> >How did you come to the conclusion it should be 452? > Like Svensson says, how do you get 452 ? > If you calculate 452/3 you get 150.(6) What I can read from the question: the predicted result should be 452. Since the formula only does what is told to do, i.e. output the number 444 with the specific input, then my conclusion is that the wrong formula is used - but it is not possible to tell what the proper formula should be without knowing what is to be calculated. Then we have the second alternative: he may had done a error while calculating the predicted number - and then the formula is indeed correct. But I wont know until told, hence my question. P.S. There are other alternatives as well, but lets leave them out for now... D.S. -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
