### unsigned-byte (Type)

##### 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`

.
