Equivalent of DB2's smallint data type

When migrating a database from DB2 to Oracle, what is the equivalent of the 'smallint' data type (of DB2) in Oracle?

Well, check in the DB2 reference how many bytes is smallint in capacity. I know in SQL Server, it is 2 bytes. 2 bytes represents a number from -2^16 to 2^16 That means 65536. The numeric Oracle equivalent is Number(5). In general, the algorithm is to see how many bytes in source DBMS, lets say N, then compute how many digits in 2^N AND define number with same amount of digits.
