System Class INTEGER

Class Precedence List:

integer, rational, real, number, t

Description:

An integer is a mathematical integer. There is no limit on the magnitude of an integer.

The types fixnum and bignum form an exhaustive partition of type integer.

Compound Type Specifier Kind:

Abbreviating.

Compound Type Specifier Syntax:

integer [lower-limit [upper-limit]]

Compound Type Specifier Arguments:

lower-limit, upper-limit---interval designators for type integer. The defaults for each of lower-limit and upper-limit is the symbol *.

Compound Type Specifier Description:

This denotes the integers on the interval described by lower-limit and upper-limit.

Notes:

The type `(integer` lower`` upper`)`, where lower and upper are most-negative-fixnum and most-positive-fixnum, respectively, is also called fixnum.

The type `(integer 0 1)` is also called bit. The type `(integer 0 *)` is also called unsigned-byte.
