Description:
------------
This example is totally false :

echo bcmul('1.34747474747', '35', 3); //47.162

If you use this line of code in your app, PHP will not round the last decimal. The value will be truncated at the third position and... here's the result :

-------> 47.161 <-------

Please at least change the doc.

- JP

Reproduce code:
---------------
//Give 47.161, not 47.162
echo bcmul('1.34747474747', '35', 3); 


Expected result:
----------------
47.162


Actual result:
--------------
47.161

I already fixed this one (because of a user note).

With the test case given by jeanphilg I still get 47.161.

robert, you're absolutely right.

nlopess, 5 years and this bug is still not corrected. Please take time to check my testcase correctly before replying that's all is OK !

Thanks,

The example in the documentation has been right since revision 219196, which was committed in 2006, so I'm pretty happy leaving this closed. :)
