>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 10.9.1.0

> 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.
