From: milahu89 at web dot de Operating system: irrelevant PHP version: 5.0.5 PHP Bug Type: Math related Bug description: new function: sgn() Description: ------------ not really a bug, but i'd like to suggest a new math-function sgn(). it would make comparison of integer values much easier (an nicer, of course ;)). i've attached an example in the srccode part. Reproduce code: --------------- <?php // comparison with if/else : if($a < $b) print("a < b"); elseif($a == $b) print("a == b"); else print("a > b"); // comparison with sgn() : function sgn($int) { if($int > 0) return 1; if($int < 0) return -1; return 0; } switch(sgn($a-$b)){ case 1: print("a > b"); case 0: print("a == b"); case -1: print("a < b"); } ?> Expected result: ---------------- depends ;) Actual result: -------------- depends ... -- Edit bug report at http://bugs.php.net/?id=35025&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35025&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35025&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35025&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35025&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35025&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35025&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35025&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35025&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35025&r=support Expected behavior: http://bugs.php.net/fix.php?id=35025&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35025&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35025&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35025&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35025&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35025&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35025&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35025&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35025&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35025&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35025&r=mysqlcfg
