Bug #72839 [Nab]: is_numeric returns false for hex strings

Edit report at https://bugs.php.net/bug.php?id=72839&edit=1 ID: 72839 Updated by: requinix@php.net Reported by: Alexander dot Blum at gmail dot com Summary: is_numeric returns false for hex strings Status: Not a bug Type: Bug Package: Unknown/Other Function Operating System: Ubuntu 16.04 PHP Version: 7.1Git-2016-08-15 (Git) Block user comment: N Private report: N New Comment: Translations affected: pt_BR, DE, KR, RU, ES, TR FR, JA, RO are already fixed. ZH is not affected because it only says "if var is numeric then true otherwise false". Since this affects multiple translations I'm going to make multiple bug reports for them.
