Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows (zip): http://snaps.php.net/win32/php5.2-win32-latest.zip For Windows (installer): http://snaps.php.net/win32/php5.2-win32-installer-latest.msi Previous Comments: ------------------------------------------------------------------------ [2008-02-22 22:20:33] kjohnson at zootweb dot com Description: ------------ For certain values, not necessarily large numbers, round() returns the value in exponential notation instead of the usual decimal format. Some of these "special" values are 1200000, 1400000, 2300000, 2400000. It seems to be just certain multiples of 100,000. Generate your own list with the code below. I suggest you start with input of: Start = 1000000 Increment = 100000 Iterations = 100 to 200 Reproduce code: --------------- <html><head><title></title></head><body> <form method="post" action="<?=$_SERVER['PHP_SELF']?>"> <!-- some recommended values for next fields: 1000000, 100000, 200 --> Start value:<input type="text" name="start"> Increment: <input type="text" name="increment"> Iterations: <input type="text" name="iterations"> <input type="submit"> </form> <? if(count($_POST)) { echo "<p>Start: ", $_POST['start'], "; Increment: ", $_POST['increment'], "</p>"; $tmp = $_POST['start']; echo round($tmp),"<br>"; for($i = 0; $i < $_POST['iterations']; $i++ ) { $tmp += $_POST['increment']; echo round($tmp),"<br>"; } } ?> </body></html> Expected result: ---------------- All values to be returned in standard decimal format, e.g., "1200000". Actual result: -------------- Certain values are returned in exponential format, e.g., "1.2E+6". ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44223&edit=1
