"This series implements CAST AS functions in scylla.
It allows to use expressions of the form CAST(x AS type) in select statements.
Primary motivation for this functions came from aggregate functions, because
function avg(.) gives rounded results for interger columns. Now it is possible
to convert such column to float/double and obtain floating point results:
SELECT ... avg(cast(x as double)), ...
Fixes #2280."
