Please answer these questions before submitting your issue. Thanks!

1. Minimal reproduce step (Required)

create table lrr_test(`COL1` int);
insert into lrr_test values(23);
select col1, radians(col1) from lrr_test where radians(col1) <> radians(23);

2. What did you expect to see? (Required)

Empty set

v8.4.0 can return correctly, this is a regression

3. What did you see instead (Required)

+------+---------------------+
| col1 | radians(col1) |
+------+---------------------+
| 23 | 0.40142572795869574 |
