Type UNSIGNED-BYTE

Supertypes:

unsigned-byte, signed-byte, integer, rational, real, number, t

Description:

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=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.

Notes:

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