Hi community, I was working on presto bug 995 ( https://issues.apache.org/jira/browse/CARBONDATA-995) in which variance of decimal values is calculated. When there is lesser number of decimal values to calculate variance in carbondata and presto then there being no difference in result. But when the dataset become large the result value varies to minor difference (in my case i am calculating it with 2000 bigdecimal values the result difference between presto and carbondata is 0.1938... ). So, should i continue looking into this issue or this much difference is fine.
-- Thanks & Regards Jatin
