Re: Need unrounded precision

Hi, I need to extract the first digit after the decimal point from a number such as 28.56018, which should be '5'. 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
