Subject [jira] [Comment Edited] (CASSANDRA-11935) Add support for arithmetic operators

---------------------------------------------------------------------

There is a issue with this ticket as it changes the serialization format of Shorts from variable
width to fixed.  This needs to be captured in the MessageService, CommitLog, and SSTable versions
so we can properly upgrade clusters to 4.0

> 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).
