Bug #55160 [Opn->Nab]: Unexpected result on bccomp when using any decimal comma locale

Edit report at https://bugs.php.net/bug.php?id=55160&edit=1 ID: 55160 Updated by: mike@php.net Reported by: everton at faccat dot br Summary: Unexpected result on bccomp when using any decimal comma locale -Status: Open +Status: Not a bug Type: Bug Package: BC math related Operating System: Ubuntu 10.04 LTS 64bits PHP Version: trunk-SVN-2011-07-08 (snap) Block user comment: N Private report: N New Comment: Nevertheless it is expected behaviour. Argument type of these functions is string. This is a bug report about an unexpected result not a feature request to implement some magic non-locale-aware string cast. Sorry :) Previous Comments: ------------------------------------------------------------------------ [2013-10-02 10:07:14] nikic@php.net @mike PHP's shitty float to string cast shouldn't impede the workings of bcmath. We've had this problem in the past several times (with stuff like JSON etc) and the solution is to use some custom printf modifier for this. ------------------------------------------------------------------------ [2013-10-02 09:29:09] mike@php.net This is actually expected behaviour because bcmath operates on strings and PHP casts numbers to strings according to locale. ------------------------------------------------------------------------ [2011-07-08 08:36:47] everton at faccat dot br added OS additional information ------------------------------------------------------------------------ [2011-07-08 08:27:56] everton at faccat dot br Description: ------------ Unexpected result on bccomp when using any decimal comma locale. 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
