Hi @DamonFool, the problem is I am not sure what to assert in a jtreg test for this scenario, there seems to be no clear way to tell if a given value is correct or not. (The result produced by the 2 formulas can be close.)

But I am definitely happy to add the test case if some further suggestions can be provided.
