How is the Number of Decimal Places Determined for Aggregated Values?

When converting higher-frequency values to lower-frequency values, the average, sum, and end-of-period aggregation methods use the same number of decimal places as the original data. For example, the monthly values of 100.1 (Jan), 100.4 (Feb), and 100.9 (March) will be averaged to a quarterly value of 100.5 (i.e., 100.467 rounded).
