note 61647 added to function.bcscale

If you don't set the default scale, be careful when you're chaining together several BC math functions - since by default, these functions will round off your values, losing accuracy very quickly: <?php $a = 1.234 $b = 2.345 $c = 7.890 $ab = bcmul($a,$b); // 2 $abc = bcmul($ab,$c); echo $abc; // 15 ?> ... compare with the answer you get when you use more decimal places: <?php $a = 1.234 $b = 2.345 $c = 7.890 bcscale(15); $ab = bcmul($a,$b); // 2.893730 $abc = bcmul($ab,$c); echo $abc; // 22.83152970 ?> ---- Server IP: 203.202.10.60 Probable Submitter: 220.239.121.53 ---- Manual Page -- http://www.php.net/manual/en/function.bcscale.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+61647 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+61647&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+61647&report=yes Search -- http://master.php.net/manage/user-notes.php
