Describe:

SELECT <column> FROM <table> brings different results, when using CPU-only configurations and GPU-used configurations.

SQL with CPU-only Config:

CREATE TABLE t1(c0 FLOAT NULL);
INSERT INTO t1(c0) VALUES('Infinity');
INSERT INTO t1(c0) VALUES(0.1);
ALTER SESSION SET EXECUTOR_DEVICE='CPU';
SELECT CAST(CAST(t1.c0 AS INT) AS BOOLEAN) FROM t1;

Result:

EXPR$0
NULL
false

SQL with GPU-used Config:

ALTER SESSION SET EXECUTOR_DEVICE='GPU';
SELECT CAST(CAST(t1.c0 AS INT) AS BOOLEAN) FROM t1;

Result:

EXPR$0
true
false

Environment:
