WebThe Hamming distance defines the number of bits that need to change in a binary value in order to produce another value. In this example we can enter a number of binary values: Hamming distance of 01,11,10 gives a Hamming distance of 1. Calc. Hamming distance of 00000, 01101, 10110, 11011 gives a Hamming distance of 3. Calc. WebFeb 17, 2014 · In hamming calculations, integers are treated as bits. The hamming distance is the number of bit differences, which can be calculated as the number of non-zero bits in the xor of the two values. For the two integers you provide, the bitwise hamming distance is indeed 40. which is 40 non-zero bits.
