Jacques Nadeau commented on DRILL-1005:
---------------------------------------
These are inexact functions against exact datatypes. Will provide implicit
cast from decimal to double later. For now, if you need this functionality you
should use [funcname](cast x as double) to explicitly cast your input.
> stddev_pop(decimal) cause internal error
