#### 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:: ¶

(`unsigned-byte`{`[`s | *`]`})

#### Compound Type Specifier Arguments:: ¶

#### 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.
