python - How to get the relative complement of a boolean numpy array ...

For boolean values, logical and bitwise operations are the same. It is therefore quite idiomatic to write v1 & ~v2 However, this is a bitwise operation, and produces a potentially unnecessary temp array. You can not write v1 and not v2 as much as you'd like to because python expects to convert the inputs to single boolean values. ...

BitwiseOperators - Python Wiki

Two's Complement binary for Negative Integers: Negative numbers are written with a leading one instead of a leading zero. So if you are using only 8 bits for your two's complement numbers, then you treat patterns from "00000000" to "01111111" as the whole numbers from 0 to 127, and reserve "1xxxxxxx" for writing negative numbers.

You may find it surprising that ~85 does not return the bit pattern 0101010 but this is just due to the two’s complement representation of integers in Python. Python bool Understanding two’s complement and knowing that Python bools are a subclass of int, it is not surprising that

Find the complement of a number - Python Forum

1's complement: 1100 0011, that means the first 1 -> - and 100 0011 is 67. You work with one Byte (=8bit), 1 is already assigned, so 7 left. 2**7 = 128. You now substract (because this is a negative value and this is how negative values are represented in binary) this value of 67; 67-128 = -61.
