--------------------------------------
Summary: Casting Floating-point types to Boolean types should be supported
Key: DRILL-5595
URL: https://issues.apache.org/jira/browse/DRILL-5595
Project: Apache Drill
Issue Type: Bug

Today, only Int and BigInt can be casted to Boolean. Casting Float / Double values to Boolean fails:
{code}
select cast(1.0 as boolean) from (values(1));
Error: SYSTEM ERROR: IllegalArgumentException: Invalid value for boolean: 1.0
select cast(t.a as boolean) from (select cast(1.0 as float) as a from (values(1))) t;
Error: SYSTEM ERROR: IllegalArgumentException: Invalid value for boolean: 1.0
{code}
