Pavel Pereslegin updated IGNITE-24934:
--------------------------------------
Description:
In the following test case the value is truncated with rounding (see
test/sql/types/timestamp/test_timestamp.test)
{code}
query T
SELECT '2008-01-01 00:00:01.9995'::TIMESTAMP(3)::VARCHAR
----
2008-01-01 00:00:02
{code}
But the same example with precision = 2 truncates value without rounding
{code:java}
assertQuery("SELECT '2024-01-01 20:08:10.999'::TIMESTAMP(2)::VARCHAR")
.returns("2024-01-01 20:08:11")
.check();
{code}
{noformat}
Expected: 2024-01-01 20:08:11 <class java.lang.String>
Actual: 2024-01-01 20:08:10.99 <class java.lang.String>
{noformat}
The same is reproduced for TIME type also.
This issue may be related to IGNITE-24889.
Looks like we don't perform round-up for numerics now, for example
{code:sql}
SELECT 10.7::INT --- 10
{code}
We should make the behavior consistent and not round the values when they are
truncated.
