Review comment:
The expected behavior is that the query will still evaluate and produce
results as long as the numerical value can be compared to the column type. For
example, the following works on MySQL and PostgreSQL.
```
create table test(intColumn int, floatColumn float);
insert into test values(5, 5.5);
insert into test values(10, 15.56);
select * from test where intColumn < 300.453;
select * from test where intColumn < 300000000000000000000000.453;
select * from test where floatColumn > 6;
```
300000000000000000000000.453 is outside the bounds of Integer datatype, so
it can't be represented as an Integer value, but gets parsed to something that
can be compared to an integer.
