WebJan 18, 2024 · Bitwise operations are usually used to set/clear/toggle/check bits in bitfields. None of these operations require nand ("and not", also known as "bit clear" is more useful). Logical operations in most modern programming languages are evaluated using short-circuit logic. So usually a branch-based approach to implementing them is needed.
