Web24 de oct. de 2015 · The answer to leading zeros in a 64 bit number is either the number of leading zeros in the first 32 bits (if any is a non-zero) or it's 32 + the number of leading zeros in the lower 32 bits. That gives you the answer to the 6th bit of the answer. You then need to find the number of leading zeros in the 32 bit number, so apply the same rules.
