Subject [jira] [Commented] (FLINK-9977) Refine the docs for Table/SQL built-in functions
Date Wed, 01 Aug 2018 08:57:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-9977?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16565004#comment-16565004

Timo Walther commented on FLINK-9977:

This problem should be discussed in a separate thread. Let's open a JIRA issue for it, if
it does not exist yet. We should first investigate if we can let Calcite convert simple literals
to double. Explicit casts are not a nice solution but at least they make the operation explicit.
If we would automatically cast the type to double we would lose precision which might be unintended.
A corresponding {{BigDecimal}} method would also return a {{BigDecimal}} and would cause high
serialization overhead for Flink applications even though a simple double would do the job.
