(2) radix-minus-one complement:
Positive: a positive number radix-minus-one complement the same as the original code,
Negative: the negative radix-minus-one complement, the sign bit is "1", the numerical part according to invert,
Floating point representation method

Floating point representation method
For example: the sign bit values
[+ 7) anti=0 0000111 B
[7] anti=1 1111000 B
Note: a. the number 0 radix-minus-one complement has two forms, namely,
[+ 0] anti=00000000 b
[0] anti=11111111 b
B. eight one's complement representation of scope: - 127 ~ + 127

How radix-minus-one complement is bitwise anti, 0 also the no 01111111
