Description:
------------
If I use number_format() with "." as decimal point and then round it with 1 decimal, it'll work fine, but not if the decimal point is ",".

I'm using WAMP5 and haven't done any changes at all to php.ini.

Reproduce code:
---------------
<?php

$number = number_format(1000000/1024, 2, ".", "");
echo "A: ".round($number, 2);


$number = number_format(1000000/1024, 2, ",", "");
echo "B: ".round($number, 2);

?>

Expected result:
----------------
A: 976.56

B: 976,56

Actual result:
--------------
A: 976.56

B: 976

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

With comma the value isn't treat as float. Then, when it is converted, the part after ',' is removed. See:

$number = number_format(1000000/1024, 2, ",", "");
var_dump($number); // string(6) "976,56"
var_dump((float) $number); // float(976)
