I've tried a few methods to accomplish this. If I use 'ini_set' I would need to know the number of digits before the decimal (which, unfortunately, I would not have access to). Then I've tried: <?php $elapsed = 28.56018; $digit = round($elapsed, 1); // rounds result is '6' $digit = number_format($elapsed, 1); // still rounds result to '6' ?> What I need is only the first digit after the decimal -- all the rest could be 'chopped' or discarded but without rounding the first digit after the decimal point. Is there any way of doing this? I'm stumped. Tia, Andre -- One way that should work regardless the number of digits before/after the decimal is: - convert to string (sprintf or typecast) - strpos the decimal - grab the char from the next position Cheers Arno -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
