Robert Stupp commented on CASSANDRA-11485:
------------------------------------------
[~nhaller], can you provide information on how to reproduce it and how the
exception exactly looks like? Also, on which version this occurs.
> ArithmeticException in avgFunctionForDecimal
> --------------------------------------------
>
> Key: CASSANDRA-11485
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11485
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: Nico Haller
> Priority: Minor
>
> I am running into issues when using avg in queries on decimal values.
> It throws an ArithmeticException in
> org/apache/cassandra/cql3/functions/AggregateFcts.java (Line 184).
> So whenever an exact representation of the quotient is not possible it will
> throw that error and it never returns to the querying client.
> I am not so sure if this is intended behavior or a bug, but in my opinion if
> an exact representation of the value is not possible, it should automatically
> round the value.
> Specifying a rounding mode when calling the divide function should solve the
> issue
