 User updated by:  oswald at jaskolla dot net
 Reported By:      oswald at jaskolla dot net
 Status:           Open
 Bug Type:         Strings related
 Operating System: Windows XP, Linux
 PHP Version:      5.2.6
 New Comment:

Description:
------------
sscanf() seems not to be locale-aware when interpreting '%f', even
though the documentation says it is. localeconv() says that after my
call to setlocale(), the comma is interpreted as decimal separator.
Still everything after the comma is omitted.

Tested environments:
Windows XP, PHP 5.2.5, Apache 2.2.8 (mpm_winnt)
Linux 2.6.9, PHP 5.2.6RC1, Apache 2.2.8 (prefork)

Reproduce code:
---------------
setlocale(LC_ALL, array('de_DE.utf-8', 'german'));
$value = sscanf('3,14159265', '%f');
echo '<div>parsed: &pi; &asymp; ', $value[0], '</div>';
echo '<div>formatted: &pi; &asymp; '; printf('%f', 3.14159265);
echo
'</div>';

Expected result:
----------------
parsed: &#960; &#8776; 3.14159265
formatted: &#960; &#8776; 3,14159265

Actual result:
--------------
parsed: &#960; &#8776; 3
formatted: &#960; &#8776; 3,14159265
