     [ https://issues.apache.org/jira/browse/DRILL-67?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexandre Beche updated DRILL-67:
---------------------------------

    Attachment: DRILL-70-2.patch.txt

Stddev function is now included.
AVG and STDDEV are implemented using online algorithm.
inputHasFloat flag is now set to false is the reset function.

I will now focus on the unit tests but where should I put them, in the file:
src/test/java/org/apache/drill/exec/ref/rops/CollapsingAggregateTest.java
