Check power of 2 bitwise
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 … WebEngineering. Computer Science.
