+     * algorithm shown would choose {@code int} values from the stated range

+     * <p>
+     * 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.
+     * <p>
+     * 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 <i>low-order</i> 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
