</div></div>I didn't take a look a the code so sorry if my suggestion is out of<br>
line. So here it is: Couldn't this be solved if each report cell value<br>
is a MyMoneyMoney object?<br>
Or they are already MyMoneyMoney objects and case the rounding themselves?<br></blockquote></div><br>They are MyMoneyMoney objects and they are rounded when the budget is calculated into the cells (different periods, currencies, and so on, make it a not so straightforward process to display the budget).<br>
<br>And you do have to round them when dealing with multiple currencies because of overflow issues. The denom starts growing very quickly and you end up very quickly with a nonsense number like -3.123412341234 :)<br><br>
