    Description

      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.
