Reynold Xin updated SPARK-9281:
-------------------------------
Labels: releasenotes (was: )
> Parse literals as decimal in SQL
> --------------------------------
>
> Key: SPARK-9281
> URL: https://issues.apache.org/jira/browse/SPARK-9281
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Reporter: Davies Liu
> Assignee: Davies Liu
> Labels: releasenotes
>
> Right now, we use double to parse all the float number in SQL. When it's used
> in expression together with DecimalType, it will turn the decimal into double
> as well.
> Also it will loss some precision when using double.
> It's better to parse the float number as decimal (we will know exactly the
> precision and scale is), it also work well with double.
> BTW, this is a break change.
