note 90389 added to function.hexdec

hexdec doesn't accept numbers following the period. What if you have a number like c20.db18? <?php function floatinghexdec($str) { list($intgr,$hex)=explode('.',$str,2); $intgr=ereg_replace("[^A-Fa-f0-9]", "", $intgr); $hex=ereg_replace("[^A-Fa-f0-9]", "", $hex); $answer=0; for($i=0;$i < strlen($hex); $i++) { $digit=hexdec(substr($hex,$i,1))/16; // .f is 15/16 because in decimal .9 is 9/10 $answer += $digit/pow(16,$i); } return hexdec($intgr)+$answer; } echo floatinghexdec("ff.ff");//255.99609375 ?> ---- Server IP: 208.69.120.35 Probable Submitter: 76.94.233.193 ---- Manual Page -- http://www.php.net/manual/en/function.hexdec.php Edit -- https://master.php.net/note/edit/90389 Del: integrated -- https://master.php.net/note/delete/90389/integrated Del: useless -- https://master.php.net/note/delete/90389/useless Del: bad code -- https://master.php.net/note/delete/90389/bad+code Del: spam -- https://master.php.net/note/delete/90389/spam Del: non-english -- https://master.php.net/note/delete/90389/non-english Del: in docs -- https://master.php.net/note/delete/90389/in+docs Del: other reasons-- https://master.php.net/note/delete/90389 Reject -- https://master.php.net/note/reject/90389 Search -- https://master.php.net/manage/user-notes.php
