=== Short integer ===
A ''short integer'' can represent a whole number that may take less storage, while having a smaller range, compared with a standard integer on the same machine.

In [[C (programming language)|C]], it is denoted by {{mono|short}}. It is required to be at least 16 bits, and is often smaller than a standard integer, but this is not required.<ref name="c99" /><ref name="drdobbsinteger" /> A conforming program can assume that it can safely store values between −(2<sup>15</sup>−1)<ref name="c-std-6.2.6.2p2">{{cite web |url=http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1570.pdf |at=section 6.2.6.2, paragraph 2|title=ISO/IEC 9899:201x |access-date=2016-06-20 |publisher=open-std.org}}</ref> and 2<sup>15</sup>−1,<ref name="c-std-5.2.4.2.1">{{cite web |url=http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1570.pdf |at=section 5.2.4.2.1|title=ISO/IEC 9899:201x |access-date=2016-06-20 |publisher=open-std.org}}</ref> but it may not assume that the range is not larger. In [[Java (programming language)|Java]], a {{mono|short}} is ''always'' a 16-bit integer. In the [[Windows API]], the datatype {{mono|SHORT}} is defined as a 16-bit signed integer on all machines.<ref name="agnerfog" />
