Description:
------------
---
From manual page: http://www.php.net/function.round
---

It is not specified that depending on php locale, the dot is replaced by comma.

it should not have this kind of behavior or being specified in the documentation.

Test script:
---------------
<?php echo "<br/>".round(2.447,2);

Expected result:
----------------
<br/>2.45

Actual result:
--------------
<br/>2,45

It is not mentioned because it has nothing to do with round(). The comma is introduced when the floating-point value is converted to string.
http://php.net/manual/en/language.types.string.php#language.types.string.casting

echo 2.447; // 2.447
echo (string)2.447; // 2,447 with an appropriate locale
