Description: ------------ PHP manual at http://ch2.php.net/manual/en/function.gmp-div-r.php claims for gmp_div_r: ----- resource gmp_div_r ( resource $n , resource $d [, int $round ] ) Calculates remainder of the integer division of n by d . The remainder has the sign of the n argument, if not zero. ----- However, print(gmp_strval(gmp_div_r(-5, 100)) . "\n"); Will result in "5", not "-5". Reproduce code: --------------- <?php print(gmp_strval(gmp_div_r(-5, 100)) . "\n"); ?> Expected result: ---------------- -5 Actual result: -------------- 5 -- Edit bug report at http://bugs.php.net/?id=43981&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43981&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43981&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43981&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43981&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43981&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43981&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43981&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43981&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43981&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43981&r=support Expected behavior: http://bugs.php.net/fix.php?id=43981&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43981&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43981&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43981&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43981&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43981&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43981&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43981&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43981&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43981&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43981&r=mysqlcfg
