| * |
| * Let q represent the number we would like to divide by. |
| * |
| * By definition of a magic divisor for N-bit unsigned integers (a number you |

| * |
| * (m * x) & (2^N - 1) = floor(x/q). |

| * |
| * Ignore the case where any of the above values equals zero; it is irrelevant |
| * for our purposes (instanced arrays). |
| * |
| * Choose x = q. Then: |
| * |
| * (m * x) & (2^N - 1) = floor(x/q). |
| * (m * q) & (2^N - 1) = floor(q/q). |
| * |
| * floor(q/q) = floor(1) = 1, therefore: |
| * |
| * (m * q) & (2^N - 1) = 1 |
| * |
| * Recall the identity that the bitwise AND of one less than a power-of-two |
| * equals the modulo with that power of two, i.e. for all x: |
| * |
| * x & (2^N - 1) = x % N |
| * |
| * Therefore: |
| * |
| * mq % (2^N) = 1 |
| * |
| * By definition, a modular multiplicative inverse of a number m is the number |
| * q such that with respect to a modulos M: |
