integer, rational, real, number, t

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.

Abbreviating.

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

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

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.
