> Spark on {{master}} at commit {{de00ac8a05aedb3a150c8c10f76d1fe5496b1df3}}
> with {{set spark.sql.ansi.enabled=true;}} as compared to the default behavior
> on PostgreSQL 16.
> Case 1:
> {code:sql}
> select tinyint(128) * tinyint(2); -- 0
> select smallint(2147483647) * smallint(2); -- -2
> select int(2147483647) * int(2); -- -2
> SELECT smallint((-32768)) * smallint(-1); -- -32768
> {code}
> With ANSI mode enabled, this case is no longer an issue. All 4 of the above
> statements now yield {{CAST_OVERFLOW}} or {{ARITHMETIC_OVERFLOW}} errors.

> {code:sql}
> spark-sql> select cast('10e-70' as float), cast('-10e-70' as float);
