bit.neg
Bitwise 'negate' (ones complement)
Prototype
n = bit.neg (a)Description
This takes one argument. It is converted to a signed 'long long' (64-bit integer). The result is the ones-complement of the number (zero bits become one, one bits become zero).
eg.
eg.
print (bit.neg (1)) --> -2
print (bit.band (14, bit.neg (8))) --> 6 (clear 8-bit)
