BitNot
BitNot[n]
gives the bitwise NOT of the integer n.
Details

- Integer mathematical function, suitable for both symbolic and numerical manipulation.
- BitNot[n] turns ones into zeros and vice versa in the binary bit representation of n.
- Integers are assumed to be represented in two's complement form, with an unlimited number of digits, so that BitNot[n] is simply equivalent to
.
- BitNot automatically threads over lists.
