Subject [jira] [Commented] (CASSANDRA-11935) Add support for arithmetic operators
Date Fri, 18 Nov 2016 08:42:58 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11935?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15676172#comment-15676172
] 

Benjamin Lerer commented on CASSANDRA-11935:
--------------------------------------------

I pushed a new patch which: 
* revert the {{preferedType}} change
* use the return type to improve the function selection (CASSANDRA-11946)
* select the operation with the same argument types than the return type when constant literals
are used

> The goal of this ticket is to add support for arithmetic operators:
> * {{-}}: Change the sign of the argument
> * {{+}}: Addition operator
> * {{-}}: Minus operator
> * {{*}}: Multiplication operator
> * {{/}}: Division operator
> * {{%}}: Modulo operator
> This ticket we should focus on adding operator only for numeric types to keep the scope
as small as possible. Dates and string operations will be adressed in follow up tickets.
> The operation precedence should be:
> # {{*}}, {{/}}, {{%}}
> # {{+}}, {{-}}
> Some implicit data conversion should be performed when operations are performed on different
types (e.g. double + int).
