Hi Michelle,
looks much better now. Not sure what you're expecting from me on this one. The error is
test(org.apache.jdo.tck.models.fieldtypes.TestArrayCollections)junit.framework.AssertionFailedError: Assertion (TestArrayCollections) failed:

so we have a series of floating point numbers that were stored in the RDBMS and when retrieved have a different precision. We know that RDBMS don't preserve the precision exactly (as shown on other TCK tests). Does the TCK not have a method to perform rou
nding so that the numbers can be compared at the precision of the value that was input ? With all of the differences above, if the actual value is rounded up or down (depending on the number) they would be identical and the test would pass.
