    • next

      private long next(int bits)
      Returns bits upper bits of random value.
      Returns:
      bits upper bits of random value
      Implementation Note:
      In Xoroshiro128++, the lower bits have to be discarded in order to ensure proper randomness. For example, to obtain a double, the upper 53 bits, instead of the lower 53 bits.
