                 * 
                 *    1) If U < 0x10000, encode U as a 16-bit unsigned integer and

                 * 
                 *    4) Assign the 10 high-order bits of the 20-bit U' to the 10 low-order
                 *       bits of W1 and the 10 low-order bits of U' to the 10 low-order
                 *       bits of W2. Terminate.
