ASF GitHub Bot updated CALCITE-6427: ------------------------------------ Labels: pull-request-available (was: ) > Use a higher precision for DECIMAL intermediate results for some aggregate > functions like STDDEV > ------------------------------------------------------------------------------------------------ > > Key: CALCITE-6427 > URL: https://issues.apache.org/jira/browse/CALCITE-6427 > Project: Calcite > Issue Type: Bug > Components: core > Affects Versions: 1.37.0 > Reporter: Mihai Budiu > Priority: Minor > Labels: pull-request-available > > Today aggregates like STDDEV are expanded into computations that use > intermediate results with the same type as the input values. Since STDDEV > squares values, this precision may prove insufficient. For DECIMAL values a > reasonable approach would be to use double the input precision and scale. > This is also related to [CALCITE-6322], [CALCITE-4924], [CALCITE-6324] -- This message was sent by Atlassian Jira (v8.20.10#820010)
