WebJul 21, 2010 · numpy.invert. ¶. Compute bit-wise inversion, or bit-wise NOT, element-wise. Computes the bit-wise NOT of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator ~. For signed integer inputs, the two’s complement is returned. In a two’s-complement system negative numbers are ... WebPython’s bitwise NOT operator ~x inverts each bit from the binary representation of integer x so that 0 becomes 1 and 1 becomes 0. This is semantically the same as calculating ~x == -x-1. For example, the bitwise NOT expression ~0 becomes -1, ~9 becomes -10, and ~32 becomes -33. As you go over the article, you can watch my explainer video ...

Web2 days ago · In-place Operators¶. Many operations have an “in-place” version. Listed below are functions providing a more primitive access to in-place operators than the usual syntax does; for example, the statement x += y is equivalent to x = operator.iadd(x, y).Another way to put it is to say that z = operator.iadd(x, y) is equivalent to the compound statement z = … WebThe '~' operator is defined as: "The bit-wise inversion of x is defined as - (x+1).
