Please reply to pollita's questions. Otherwise we have to assume
that there is no bug.

Is there *anywhere* in your code/config/webserver where you set bcmath.scale INI entry?

The extra zeros can result from a non-zero bcmath.scale, though the question then is "Why is
scale zero sometimes, then non-zero other times?"  The problem *could* be a threading issue, so
I'd ask if you're using PHP in a threaded environment.

Description:
------------
When you do simple integer division with bcdiv some times the result have trailing 0 and other times
is a simply integer (without .000000).

For example with bcdiv('4163592965659328', 32) some times return
"130112280176854" but other times return "130112280176854.0000000000".

It appeared to be totally random as you refresh the page.

I have version 5.5.9. I have searched in the bugs but I didn't found any similar bug. Also I
know I must use the last version of php to report a bug but I can't do it (company limitation).

Note to use the hard refresh in the test script so the page isn't cached.

Test script:
---------------
<!DOCTYPE HTML>
<html>
    <body>
        <?php
            echo bcdiv('4163592965659328', 32);
        ?>
    </body>
</html>

Expected result:
----------------
130112280176854

Actual result:
--------------
130112280176854.0000000000
