> Given this table:
> ij> connect 'jdbc:derby:memory:db;create=true';
> ij> create table t(x bigint);
> 0 rows inserted/updated/deleted
> ij> insert into t values 9223372036854775805, 9223372036854775806, 9223372036854775807;
> 3 rows inserted/updated/deleted
> A query that uses an IN list that contains all the three values actually stored in the
table, returns all three rows as expected:
> ij> select * from t where x in (9223372036854775805, 9223372036854775806, 9223372036854775807);
> X                   
> --------------------
> 9223372036854775805 
> 9223372036854775806 
> 9223372036854775807 
> 3 rows selected
> However, if we add a value whose type precedence is higher, like a DOUBLE value, and
that value happens to be equal to the approximation of the other values in the IN list when
they are cast from BIGINT to DOUBLE, only one row is returned:
> ij> select * from t where x in (9223372036854775805, 9223372036854775806, 9223372036854775807,
9.223372036854776E18);
> X                   
> --------------------
> 9223372036854775805 
> 1 row selected
> I believe this query should return all three rows too.
