Description:
------------
The result returned by bcmul() with the factor X (greater than 0) and 0.00001 is 0 - it's not the expected result.

Reproduce code:
---------------
// Does not work - result is 0:
bcmul(1, 0.00001, 5);

// This workaround does it - result 0.00001:
bcdiv(bcmul(1, 0.00010, 5), 10, 5);

Expected result:
----------------
The correct result 0.00001

Actual result:
--------------
0

If you pass the numbers as strings (as expected, although the manual has it wrong in the example), this works fine:

bcmul("1", "0.00001", 5);

Reclassified as documentation issue. (the bad examples in bcmath section)

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
