Description:
------------
When using printf, zero fill, floats, and negative numbers, PHP 4.3.9 on Windows XP Pro SP1 generates null characters at the end of the number that should not be there.
Passing a negative number, i.e. -1, into the format string "%0.2f" will give an invalid result, i.e. "-1.00[NULL]" where [NULL] is the 0th byte.

Reproduce code:
---------------
<?
printf("%0.2f<br />", 1.51555);     //ok
printf("%0.2f<br />", -1.51555);    //broken
printf("%0.2f<br />", -1);          //broken
printf("%.2f<br />", -1.5);         //ok
printf("%.2f<br />", -1.51555);     //ok
printf("%0.2f<br />", 1.51555);     //ok
?>

Expected result:
----------------
I expect "-1.00" or appropriately rounded values with no trailing null bytes.

Actual result:
--------------
Cannot paste output, it is truncated at the first null byte.
