WebAccording to CLRS. A prime not too close to an exact power of 2 is often a good choice for m. while calculating hash values through the division method, where the hash function is: h (k) = k mod m. While it makes sense to not choose m as a power of 2, how is the distance of m from an exact power of 2 going to affect the hashing? data-structures. WebFeb 15, 2014 · Why only use primes for Hash function division method. Hashing using division method means h (k) = k mod m . I read that. m should not be power of 2. This is because if m = 2^p, h becomes just the p lowest-order bits of k. Usually we choose m to be a prime number not too close to a power of 2.
