Author #38573 [NEW]: BCMath bcmul not round the last decimal

From: jeanphilg at hotmail dot com
Operating system: Unix
PHP version: Irrelevant
PHP Bug Type: Documentation problem
Bug description: BCMath bcmul not round the last decimal

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
