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 this bug report at http://bugs.php.net/?id=43981&edit=1
