Hi, without knowing much about what's going on, note that user=> (reduce + [15.00M 15.01M 3.00M 3.01M]) 36.02M user=> (with-precision 3 (reduce + [15.00M 15.01M 3.00M 3.01M])) 36.0M
So an intermediate step in the calculation is rounded down to 3 decimals and that rounding error is carried through. So the "9M" with 3-precision would mean "9.00M". Amazing! It might be getting in your way here, but functions changing their operation because they were called via "with-precision" speaks to a flexibility that I've only seen in Lisps.
