Review request for KMymoney.


Changes
-------

Also take care of the shares of a split so that their precision does not go beyond the precision of the security. Testcase and logic got enhanced.


Bugs: 345655

Repository: kmymoney


Description
-------

The problem described in bug 345655 is caused by a fraction of the splits value that is larger than the fraction of the accounts currency. This leads to the effect, that values are displayed with correct value but the underlying value used for calculations is not equal to the amount displayed. This will end up in KMyMoney presenting the user strange messages like 'Unassigned value of 0.00' which do not make sense. The difference is in reality between 0 and 0.01, e.g. 0.008.

The attached patch resolves this problem by rounding the numbers to the correct fraction of the referrenced account.
