Detailed Description

Attribute: Store a signed integer in One's Complement format.

When applied to a $k$ -Bit-Integer, let $x_{k-1},x_{k-2},\dots,x_0$ denote its raw bits with $x_{k-1}$ being the most significant and $x_0$ the least significant one. Then $x_{k-1}$ is the sign bit. The value of the integer is:

$X = (1 - 2 \cdot x_{k-1}) \cdot \sum_{i=0}^{k-2}{2^i \cdot y_i}$

with

$y_i = \begin{cases} x_i & x_{k-1} = 0\\ 1-x_i & x_{k-1} = 1 \\ \end{cases}$

The range for a signed $k$ -Bit-Integer in One's complement format is $[-2^{k-1}+1;2^{k-1}-1]$ . There are 2 representations for zero.
