WebApr 5, 2024 · The & operator is overloaded for two types of operands: number and BigInt.For numbers, the operator returns a 32-bit integer. For BigInts, the operator returns a BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt AND if both operands becomes BigInts; otherwise, it converts both operands to 32-bit … Bash allows us to use bitwise operators via expr, let, declare, or arithmetic expansion. All the following examples of bitwise ANDare therefore valid. But, we should be aware that many operators need to be escaped or quoted: Below, we’ll use only the last type of $((…)), which is the most straightforward to … See more Bitwise operators allow simple, fast, and basic operations on the individual bits of the variables involved. They may seem a heritage of the assembly language era. Yet, we still need them in cryptography, computer graphics, … See more We can represent the same numerical quantities with different bases, using methods to convert from one base to another. In particular, … See more In this article, we’ve seen how Bash represents numbers by bits and what basic operations we can do on these bits. Knowledge of the basic rules of Boolean algebra is not strictly necessary, but it will undoubtedly help us … See more
