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

The atomic type specifier signed-byte denotes the same type as is denoted by the type specifier integer; however, the list forms of these two type specifiers have different semantics.

Abbreviating.

• :signed-byte [s | *]

• s - a positive integer.

This denotes the set of integers that can be represented in two's-complement form in a byte of s bits. This is equivalent to (integer lower upper), where lower and upper, respectively, are -2s - 1 and 2s - 1 - 1. The type signed-byte or the type (signed-byte *) is the same as the type integer.
