PLS_INTEGER is a PL/SQL data type used for storing signed integers. PLS_INTEGER is defined in the STANDARD package as a subtype (or rather a synonym) of BINARY_INTEGER. Variables declared as PLS_INTEGER can be assigned values between -2**31 to 2**31-1 (-2,147,483,648 to 2,147,483,647).

PLS_INTEGER and BINARY_INTEGER Data Types. The PL/SQL data types PLS_INTEGER and BINARY_INTEGER are identical. For simplicity, this document uses PLS_INTEGER to mean both PLS_INTEGER and BINARY_INTEGER. The PLS_INTEGER data type stores signed integers in the range -2,147,483,648 through 2,147,483,647, represented in 32 bits.

Feb 10, 2012 · PLS_INTEGER values require less storage than NUMBER values. Also, PLS_INTEGER operations use machine arithmetic, so they are faster than NUMBER and BINARY_INTEGER operations, which use library arithmetic. Having this, if i add two numbers, one of NUMBER data type and one of pls_integer (or simple_integer) data type, where will this operation be ...

In Oracle documentation there is following sentence related to PLS_INTEGER:-"PLS_INTEGER operations use hardware arithmetic, so they are faster than NUMBER operations, which use library arithmetic." Can you please explain me the terms "hardware arithmetic" and "library arithmetic". What is the difference between them. Thanks and Best Regards

Another difference between pls_integer and binary_integer is that when calculations involving a pls_integer overflow the PL/SQL engine will raise a run time exception. But, calculations involving a binary_integer will not raise an exception even if there is an overflow.
