note 73522 added to ref.bc

Code below implements standard rounding on 5 or higer round up, else don't round. There wasn't a round function for the BC functions, so here is a simple one that works. Same args as round, except takes strings and returns a string for more BC operations. ---------------- function roundbc($x, $p) { $x = trim($x); $data = explode(".",$x); if(substr($data[1],$p,1) >= "5") { //generate the add string. $i=0; $addString = "5"; while($i < $p) { $addString = "0" . $addString; $i++; }//end while. $addString = "." . $addString; //now add the addString to the original fraction. $sum = bcadd($data[0] . "." . $data [1],$addString,$p+1); //explode the result. $sumData = explode(".",$sum); //now, return the correct precision on the rounded number. return $sumData[0] . "." . substr($sumData[1],0,$p); } else { //don't round the value and return the orignal to the desired //precision or less. return $data[0] . "." . substr($data[1],0,$p); }//end if/else. }//end roundbc. ---- Server IP: 64.71.164.2 Probable Submitter: 64.207.232.142 (proxied: 1.0 WIN-WEBFILTER) ---- Manual Page -- http://www.php.net/manual/en/ref.bc.php Edit -- https://master.php.net/note/edit/73522 Del: integrated -- https://master.php.net/note/delete/73522/integrated Del: useless -- https://master.php.net/note/delete/73522/useless Del: bad code -- https://master.php.net/note/delete/73522/bad+code Del: spam -- https://master.php.net/note/delete/73522/spam Del: non-english -- https://master.php.net/note/delete/73522/non-english Del: in docs -- https://master.php.net/note/delete/73522/in+docs Del: other reasons-- https://master.php.net/note/delete/73522 Reject -- https://master.php.net/note/reject/73522 Search -- https://master.php.net/manage/user-notes.php
