1310 *
1311 * Let q represent the number we would like to divide by.
1312 *
1313 * By definition of a magic divisor for N-bit unsigned integers (a number you
1314 * multiply by to magically get division), m is a number such that:
1315 *
1316 * (m * x) & (2^N - 1) = floor(x/q).
1317 * for all x on Z where 0 <= x < 2^N
1318 *
1319 * Ignore the case where any of the above values equals zero; it is irrelevant
1320 * for our purposes (instanced arrays).
1321 *
1322 * Choose x = q. Then:
1323 *
1324 * (m * x) & (2^N - 1) = floor(x/q).
1325 * (m * q) & (2^N - 1) = floor(q/q).
1326 *
1327 * floor(q/q) = floor(1) = 1, therefore:
1328 *
1329 * (m * q) & (2^N - 1) = 1
1330 *
1331 * Recall the identity that the bitwise AND of one less than a power-of-two
1332 * equals the modulo with that power of two, i.e. for all x:
1333 *
1334 * x & (2^N - 1) = x % N
1335 *
1336 * Therefore:
1337 *
1338 * mq % (2^N) = 1
1339 *
1340 * By definition, a modular multiplicative inverse of a number m is the number
1341 * q such that with respect to a modulos M:
1342 *
1343 * mq % M = 1
1344 *
1345 * Therefore, q is the modular multiplicative inverse of m with modulus 2^N.
