Bug #77278 [Ver]: floatval(strval(value)) truncates if locale's decimal_point isn't a period

Edit report at https://bugs.php.net/bug.php?id=77278&edit=1 ID: 77278 Updated by: requinix@php.net Reported by: spam2 at rhsoft dot net Summary: floatval(strval(value)) truncates if locale's decimal_point isn't a period Status: Verified Type: Bug Package: Scripting Engine problem PHP Version: Irrelevant Block user comment: N Private report: N New Comment: You can't blame PHP for Tidy's problem. If they change locale (already a dangerous operation since it's not thread-safe) and then don't revert it to the previous setting when they're done, that's their fault. Previous Comments: ------------------------------------------------------------------------ [2018-12-10 21:33:13] spam2 at rhsoft dot net working as intended? a random linked library calls locale and the whole behavior of internal php typecast changes for every follow-up code in a PHP application is intended? really? ------------------------------------------------------------------------ [2018-12-10 21:29:50] nikic@php.net I think we should get rid of the locale-dependent float to string cast in PHP 8, but for now this is working as "intended". We should definitely *not* make string to float cast locale-sensitive as well, that would only make a bad situation worse. ------------------------------------------------------------------------ [2018-12-10 19:37:59] requinix@php.net var_dump(setlocale(LC_NUMERIC, "de_DE", "German_Germany")); var_dump(1 / 2); float 0,5 var_dump(strval(1 / 2)); // string "0,5" var_dump(floatval(strval(1 / 2))); // float 0 ------------------------------------------------------------------------ [2018-12-10 18:47:07] spam2 at rhsoft dot net > but that there's an inconsistency between casting floats > to strings and strings to floats when it comes to the decimal symbol? that's exactly the point - oustide of format functions my locale de_DE.UTF-8 normally don't matter and shouldn't do so but afer a simple tidy call anywhere every following php code doing type casts on float values becomes a lottery ------------------------------------------------------------------------ [2018-12-10 18:40:04] requinix@php.net I assume you're not trying to use this bug report for Tidy changing locale but that there's an inconsistency between casting floats to strings and strings to floats when it comes to the decimal symbol? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
