RE: [PHP] Need unrounded precision

May be this will work $elapsed = 28.56018; $elapsed_rel = (int) 28.56018; $elapsed_deci = $elapsed - $elapsed_rel; $deci = ((int) ($elapsed_deci * 10))/10; $final = $elapsed_rel + $deci; With regards, Chetan Dattaram Rane | Software Engineer | Persistent Systems chetan_rane@persistent.co.in  | Cell: +91 9766646714 | Tel: +91 (0832) 30 79228 Innovation in software product design, development and delivery- www.persistentsys.com -----Original Message----- From: Arno Kuhl [mailto:akuhl@telkomsa.net] Sent: Monday, October 12, 2009 12:07 PM To: 'Andre Dubuc'; php-general@lists.php.net Subject: RE: [PHP] Need unrounded precision -----Original Message----- From: Andre Dubuc [mailto:aajdubuc@webhart.net] Sent: 02 January 2010 03:20 AM To: php-general@lists.php.net Subject: [PHP] 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 -- 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 DISCLAIMER ========== This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
