This is interesting, I would think that the 5_4 functionality is more correct, 
because you're adding a null character as the thousands separator so the string is 
becoming: 
1\0328\0370\0011.72399998

Internally a null character terminates a C style string.  I would think the 
appropriate fix would be to limit the fourth parameter to displayable characters.

This probably changed as a result of a bugfix somewhere.

Description:
------------
when I run the test code on php5.3. php returns 1328370011.72399998.
but in php5.4 that returns 1.

i don't know which behavior is correct. i think it should be returns same result.

Test script:
---------------
<?php
echo number_format(1328370011.724,"8",".", "\0");

Expected result:
----------------
1328370011.72399998

Actual result:
--------------
1
