Only the negative range goes to 2147483648 and you used positive value which is
ranged till 2147483647,
so this should work
SELECT CAST('-2147483648' as numeric) FROM RDB$DATABASE
SELECT CAST('-2147483648' as numeric(9,0)) FROM RDB$DATABASE

Subject: RE: [firebird-support] Cast as Numeric without parenthesis
I would expect numbers in the range -2147483648 to +2147483647 to be
accepted (the size of an integer), and then there’s a separate field for
storing whether things are shifted to the left or right. I’ve no experience or
theoretical knowledge confirming this, but your examples would fit such a
description. Hence, I would guess NUMERIC to default to NUMERIC(9, 0).
I've confirmed that
SELECT CAST('2147483647' as numeric) FROM RDB$DATABASE
SELECT CAST('2147483647' as numeric(9,0) FROM RDB$DATABASE
both are accepted, whereas
SELECT CAST('2147483648' as numeric) FROM RDB$DATABASE
SELECT CAST('2147483648' as numeric(9,0) FROM RDB$DATABASE
are rejected.
HTH,
