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. For signed integer inputs, the two’s complement is returned. In a two’s-complement system negative numbers are represented by th...
All floating-point numbers must have a decimal part, which can be 0, which is designed to distinguish floating-point numbers from integer types. There are two kinds of decimal representation and scientific notation. Scientific numeration uses the letter e or E as a symbol for a power, with ...

Notice that bit-length, which is the number of binary digits, varies greatly across the characters. The euro sign (€) requires fourteen bits, while the rest of the characters can comfortably fit on seven bits.Note: Here’s how you can check the bit-length of any integer number in ...
