[jira] [Created] (SPARK-29638) Spark handles 'NaN' as 0 in sums

Dylan Guedes created SPARK-29638:
------------------------------------

             Summary: Spark handles 'NaN' as 0 in sums
                 Key: SPARK-29638
                 URL: https://issues.apache.org/jira/browse/SPARK-29638
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Dylan Guedes


Currently, Spark handles 'NaN' as 0 in window functions, such that 3+'NaN'=3. PgSQL, on the other hand, handles the entire result as 'NaN', as in 3+'NaN' = 'NaN'
