1343 *
1344 * Let q represent the number we would like to divide by.
1345 *
1346 * By definition of a magic divisor for N-bit unsigned integers (a number you
1347 * multiply by to magically get division), m is a number such that:
1348 *
1349 * (m * x) & (2^N - 1) = floor(x/q).
1350 * for all x on Z where 0 <= x < 2^N
1351 *
1352 * Ignore the case where any of the above values equals zero; it is irrelevant
1353 * for our purposes (instanced arrays).
1354 *
1355 * Choose x = q. Then:
1356 *
1357 * (m * x) & (2^N - 1) = floor(x/q).
1358 * (m * q) & (2^N - 1) = floor(q/q).
1359 *
1360 * floor(q/q) = floor(1) = 1, therefore:
1361 *
1362 * (m * q) & (2^N - 1) = 1
1363 *
1364 * Recall the identity that the bitwise AND of one less than a power-of-two
1365 * equals the modulo with that power of two, i.e. for all x:
1366 *
1367 * x & (2^N - 1) = x % N
1368 *
1369 * Therefore:
1370 *
1371 * mq % (2^N) = 1
1372 *
1373 * By definition, a modular multiplicative inverse of a number m is the number
1374 * q such that with respect to a modulos M:
1375 *
1376 * mq % M = 1
1377 *
1378 * Therefore, q is the modular multiplicative inverse of m with modulus 2^N.
