If an operand is a fraction, and the other is zero, the result seems to be wrong. Test script: --------------- <?php print setlocale(LC_ALL, "C")."\n"; print 1.1."\n"; print bccomp(1.1, 0)."\n"; //changing locale to a country which uses decimal comma print setlocale(LC_ALL, "en_DK.UTF-8")."\n"; print 1.1."\n"; print bccomp(1.1, 0)."\n"; print setlocale(LC_ALL, "pt_BR.UTF-8")."\n"; print 1.1."\n"; print bccomp(1.1, 0)."\n"; ?> Expected result: ---------------- C 1.1 1 en_DK.UTF-8 1,1 1 pt_BR.UTF-8 1,1 1 Actual result: -------------- C 1.1 1 en_DK.UTF-8 1,1 0 pt_BR.UTF-8 1,1 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55160&edit=1
