# Exact Numeric (Integer) Datatypes

Learn about exact numeric (integer) datatypes.

Replication
Server supports these exact numeric (integer) datatypes:

`<bigint>`– whole numbers between -2^{63}and +2^{63}- 1 (-9,233,372,036,854,775,808 and +9,233,372,036,854,775,807), inclusive`<int>`– whole numbers between -2^{31}and +2^{31 }- 1 (-2,147,483,648 and +2,147,483,647), inclusive`<smallint>`– whole numbers between -2^{15}and +2^{15}- 1 (-32,768 and +32,767), inclusive`<tinyint>`– positive whole numbers between 0 and 255, inclusive`<unsigned bigint>`– whole numbers between 0 and 18,446,744, 073, 709,551,615, inclusive`<unsigned int>`– whole numbers between 0 and 4,294,967,295, inclusive`<unsigned smallint>`– whole numbers between 0 and 65535, inclusive`<unsigned tinyint>`– whole numbers between 0 and 255, inclusive.

The `<rs_address>` datatype,
which uses the underlying datatype `<int>`, is
used in a special method of subscription resolution. See the Replication Server Administration Guide Volume 1 for more information on the `<rs_address>` datatype.
