Editing Integer (computer science) (section)

=== Long integer ===
A ''long integer'' can represent a whole [[integer]] whose [[range (computer science)|range]] is greater than or equal to that of a standard integer on the same machine.

In [[C (programming language)|C]], it is denoted by {{mono|long}}. It is required to be at least 32 bits, and may or may not be larger than a standard integer. A conforming program can assume that it can safely store values between −(2<sup>31</sup>−1)<ref name="c-std-6.2.6.2p2" /> and 2<sup>31</sup>−1,<ref name="c-std-5.2.4.2.1" /> but it may not assume that the range is not larger.
