Subject [jira] [Commented] (HIVE-5022) Decimal Arithmetic generates NULL value
Date Thu, 21 Nov 2013 18:26:37 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13829192#comment-13829192

Xuefu Zhang commented on HIVE-5022:
-----------------------------------

Since I have been working on HIVE-3976 and its relatives and since this is closely related
to decimal precision/scale handling, I take this issue going forward. Hopefully, this will
be fixed when HIVE-3976 and the related are completed.

> When a decimal division is the first operation, the quotient cannot be multiplied in
a subsequent calculation. Instead, a NULL is returned. 
> The following yield NULL results:
> select (cast (4.53 as decimal) / cast(25.86 as decimal)) * cast(0.087 as decimal) from
<tablename> limit 1;
> select cast (4.53 as decimal) / cast(25.86 as decimal) * cast(0.087 as decimal) from
<tablename> limit 1;
> If we move the multiplication operation to be first, then it will successfully calculate
the result.
