The atomic type specifier unsigned-byte denotes the same
type as is denoted by the type specifier (integer 0 *).
- Compound Type Specifier Kind:
-
Abbreviating.
- Compound Type Specifier Syntax:
-
(unsigned-byte [s | *])
- Compound Type Specifier Arguments:
-
s - a positive integer.
- Compound Type Specifier Description:
-
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=2s, or
to (integer 0 n) for n=2s-1.
The type unsigned-byte or
the type (unsigned-byte *) is the same as
the type (integer 0 *), the set of non-negative integers.
- Notes:

The type (unsigned-byte 1) is also called bit.
