Maybe CHECK (goose >= 100 AND goose <= -100)  works better, But if :

INSERT INTO test VALUES (1, 59.2);
INSERT INTO test VALUES (1, 59.24);
INSERT INTO test VALUES (1, 59.26);
INSERT INTO test VALUES (1, 59.2678);

The INSERT action still can be done. What I want is just how to limit the length of the insert value, you can just type
formatlike 59.22, only four digits length. 

Thank you.
