    Description

      According to MDEV-274, CAST from INET6 to anything other than CHAR or BINARY should produce an error. It doesn't for FLOAT (while it does for DOUBLE):

      create table t1 (a inet6);
      		 
      insert into t1 values ('::');
      		 
      select cast(a as float) from t1;
