integer

A whole number. In programming, sending the number 123.398 to an integer function would return 123. Integers can be signed (positive or negative) or unsigned (always positive). If signed, the leftmost bit is used as the sign bit, and the maximum value of each sign is thus cut in half. For example, an 8-bit unsigned integer stores the values 0 to 255, whereas an 8-bit signed integer can store -128 to +127. See integer arithmetic and floating point.

In this section, we introduce the lattice of signed integer partitions P(n, r), and we examine some of its basic properties.
This claim assumes that the addends and sum do not exceed the range of integer representation, which is -2,147,483,648 to -2,147,483,647 for the default 4-byte signed integer. The error in the statistical problem described above, in which integer addition was used, arose because the sum of the squares of the 500 integers exceeded 2,147,483,647.
It should be specified, however, that the functions 1rint and 11rint and their single- and extended-precision equivalents convert to signed integers only.
Parameters <n> and <m> are valid, signed integers which cause either the nth or the nth through the mth line(s) to be displayed.
