unsigned-byte, signed-byte, integer, rational,
real,
number, t
The atomic type specifier unsigned-byte denotes the same
type as is denoted by the type specifier (integer 0 *)
.
Abbreviating.
(unsigned-byte
{[
s | *]
})
s—a positive integer.
This denotes the set of non-negative integers that can be
represented in a byte of size s (bits).
This is equivalent
to (mod m)
for m=2^s, or
to (integer 0 n)
for n=2^s-1.
The type unsigned-byte or
the type (unsigned-byte *)
is the same as
the type (integer 0 *)
, the set of non-negative integers.
The type (unsigned-byte 1)
is also called bit.
