note 111460 added to function.log

If you just need to check if N is a perfect power of Base, log() is SLOW compared to a WHILE construct that will be 2x faster! Tested on range: 1 ... 20.000.000 => while() is 2.105 times faster <?php $number='fill in your number here' $base='fill in requested base here'; //use when the power is needed $pow=0;do { $number/=$base;$pow++; } while ($number>1); if ($number==1) print $base.'^'.$pow; else print 'False'; //use when just a check is needed do $number/=$base; while ($number>1); if ($number==1) print 'True'; else print 'False'; ?> ---- Server IP: 69.147.83.199 Probable Submitter: 188.27.20.46 ---- Manual Page -- http://php.net/manual/en/function.log.php Edit -- https://master.php.net/note/edit/111460 Del: integrated -- https://master.php.net/note/delete/111460/integrated Del: useless -- https://master.php.net/note/delete/111460/useless Del: bad code -- https://master.php.net/note/delete/111460/bad+code Del: spam -- https://master.php.net/note/delete/111460/spam Del: non-english -- https://master.php.net/note/delete/111460/non-english Del: in docs -- https://master.php.net/note/delete/111460/in+docs Del: other reasons-- https://master.php.net/note/delete/111460 Reject -- https://master.php.net/note/reject/111460 Search -- https://master.php.net/manage/user-notes.php
