WebThe multiplication method. The multiplication method for creating hash functions operates in two steps. First, we multiply the key k by a constant A in the range 0< A < 1 and extract the fractional part of kA. Then, we multiply this value by m and take the floor of the result. In short, the hash function is h (k) = ⌊m (kA mod 1)⌋, where ...
