Budget: Don't round any of the summary dollar values

In the Summary tab, the total Planned, Spent, and Remaining are shown in the center of a pie chart. These numbers are rounded to whole dollars. Please have these numbers show the precise total, or at least provide some setting/option for this.

At the end of each month I want to know the exact value of these, particularly the exact amount spent that month, and because they are rounded I need to manually add up the sub-categories below.
