#39027 [NEW]: Modulus by 0 gives no warning, while division does

From: ludicruz at yahoo dot com Operating system: linux 26.17 PHP version: 5.1.6 PHP Bug Type: *Math Functions Bug description: Modulus by 0 gives no warning, while division does Description: ------------ taking a modulus with 0 does not give a warning or an error rather it returns a boolean false. dividing by 0 gives a warning. I think for consistancies sake (since it is practically the same operation depending on architecture) both should either give a warning or both should return boolean false; Reproduce code: --------------- <?php var_dump(1/0); var_dump(1%0); ?> Expected result: ---------------- Warning: Division by zero in /srv/www/hosts/seniorcaringcall.ithinc.net/public_html/tmp.php on line 2 bool(false) Warning: Division by zero in /srv/www/hosts/seniorcaringcall.ithinc.net/public_html/tmp.php on line 3 bool(false) //OR bool(false) bool(false) Actual result: -------------- Warning: Division by zero in /srv/www/hosts/seniorcaringcall.ithinc.net/public_html/tmp.php on line 2 bool(false) bool(false) -- Edit bug report at http://bugs.php.net/?id=39027&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39027&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39027&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39027&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39027&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39027&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39027&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39027&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39027&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39027&r=support Expected behavior: http://bugs.php.net/fix.php?id=39027&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39027&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39027&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39027&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39027&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39027&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39027&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39027&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39027&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39027&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39027&r=mysqlcfg
