The hedge "approx + * imately" is used in the foregoing description only because the next + * method is only approximately an unbiased source of independently chosen + * bits. If it were a perfect source of randomly chosen bits, then the + * algorithm shown would choose {@code int} values from the stated range + * with perfect uniformity. + *

+ * The algorithm is slightly tricky. It rejects values that would result in + * an uneven distribution (due to the fact that 2^31 is not divisible by n). + * The probability of a value being rejected depends on n. The worst case is + * n=2^30+1, for which the probability of a reject is 1/2, and the expected + * number of iterations before the loop terminates is 2. + *

+ * The algorithm treats the case where n is a power of two specially: it + * returns the correct number of high-order bits from the underlying + * pseudo-random number generator. In the absence of special treatment, the + * correct number of low-order bits would be returned. Linear + * congruential pseudo-random number generators such as the one implemented + * by this class are known to have short periods in the sequence of values + * of their low-order bits. Thus, this special case greatly increases the + * length of the sequence of values returned by successive calls to this + * method if n is a small power of two. + * + * @param bound the upper bound (exclusive).
