note 98216 added to language.types.float

In some cases you may want to get the maximum value for a float without getting "INF". var_dump(1.8e308); will usually show: float(INF) I wrote a tiny function that will iterate in order to find the biggest non-infinite float value. It comes with a configurable multiplicator and affine values so you can share more CPU to get a more accurate estimate. I haven't seen better values with more affine, but well, the possibility is here so if you really thing it's worth the cpu time, just try to affine more. Best results seems to be with mul=2/affine=1. You can play with the values and see what you get. The good thing is this method will work on any system. <?php function float_max($mul = 2, $affine = 1) { $max = 1; $omax = 0; while((string)$max != 'INF') { $omax = $max; $max *= $mul; } for($i = 0; $i < $affine; $i++) { $pmax = 1; $max = $omax; while((string)$max != 'INF') { $omax = $max; $max += $pmax; $pmax *= $mul; } } return $omax; } ?> ---- Server IP: 219.94.145.73 Probable Submitter: 122.18.184.200 ---- Manual Page -- http://www.php.net/manual/en/language.types.float.php Edit -- https://master.php.net/note/edit/98216 Del: integrated -- https://master.php.net/note/delete/98216/integrated Del: useless -- https://master.php.net/note/delete/98216/useless Del: bad code -- https://master.php.net/note/delete/98216/bad+code Del: spam -- https://master.php.net/note/delete/98216/spam Del: non-english -- https://master.php.net/note/delete/98216/non-english Del: in docs -- https://master.php.net/note/delete/98216/in+docs Del: other reasons-- https://master.php.net/note/delete/98216 Reject -- https://master.php.net/note/reject/98216 Search -- https://master.php.net/manage/user-notes.php
