> -----------------------------------------
>
> Key: PHOENIX-1660
> URL: https://issues.apache.org/jira/browse/PHOENIX-1660
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Labels: Java, SQL, gsoc2015, mentor
>
> Take a look at the typical math functions that are implemented in relational
> database systems
> (http://www.postgresql.org/docs/current/static/functions-math.html) and
> implement the same for Phoenix in Java following this guide:
> http://phoenix-hbase.blogspot.com/2013/04/how-to-add-your-own-built-in-function.html
> Examples of missing functions include POWER, LOG, EXP, SQRT, CBRT, etc. As a
> guide, examine how ROUND is implemented in Phoenix as an abstract function
> with concrete functions per type: long, decimal, and date/time types.
