12.2.9 signed-byte Type

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.

Compound Type Specifier Kind:

Compound Type Specifier Syntax:
(signed-byte [s | *])

Compound Type Specifier Arguments:
s - a positive integer.

Compound Type Specifier Description:
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 -2s-1 2s-1-1). The type signed-byte or the type (signed-byte *) is the same as the type integer.
