[jira] [Commented] (SPARK-40143) ANSI mode: allow explicitly casting fraction strings as Integral types

    [ https://issues.apache.org/jira/browse/SPARK-40143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17676435#comment-17676435 ] 

Gengliang Wang commented on SPARK-40143:
----------------------------------------

It's hard to define which cast(string as int) syntax outside the explicit cast and implicit cast.
Given our current Cast implementation is complicated enough, I will close this one for now.

> It's part of the ANSI SQL standard, and more consistent with the non-ansi casting. We can have different behavior for implicit casting to avoid `'1.2' = 1` returns true.
