#17079 [Opn->Bgs]: setlocale changes the internal representation of floats

ID: 17079 Updated by: iliaa@php.net Reported By: jonathan@tricolon.com -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: Red Hat Linux 7.1 PHP Version: 4.3.0 RC2 Assigned To: hholzgra New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php If you switch to a locale where the float separator is ',' then when it comes to output the data back to the user the float decimal point will be depedant on the specified locale. Internally however it'll always be '.'. Previous Comments: ------------------------------------------------------------------------ [2002-12-16 08:56:08] jonathan@tricolon.com > You should not use ',' to represent floats > ALWAYS use '.' regardless of locale. This is exactly the problem. When the locale is changed to Dutch the internal representation of floats is changed. The separator used is changed to ','. This behaviour is incorrect and should be fixed. Check my initial and second post for a detailed description.
