I am doing some summing in Queries and keep getting
numebrs with a large number of decimal places (Ex:
38.8500000000001).

The numbers in the tables these calculations are based on
have three decimal places at the most. I have tried to
change properties in the Table, Query, and even Report and
nothing seems to change the appearance of these values.

Is there something I can do?

Floating point (Single, Double) data types do not guarantee
100% accuracy, not even if you do the math with pencil and
paper (try to write down the decimal value of 1/3).

Generally, you can just ignore such small inaccuracies by
specifying a format with fewer decimal places and the number
will be rounded so you won't see these little discrepencies.
