[jira] [Created] (CASSANDRA-11485) ArithmeticException in avgFunctionForDecimal

Nico Haller created CASSANDRA-11485:
---------------------------------------

             Summary: 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
