Are the high bits of the engine's output known to have better statistical properties than the low bits of the output? This property is set by checking the value of an optional enum named preferHighBits. If the property is missing it is treated as false.

This should be specified as true for: <ul> <li>linear congruential generators with power-of-2 modulus</li> <li>xorshift+ family</li> <li>xorshift* family</li> <li>in principle any generator whose final operation is something like multiplication or addition in which the high bits depend on the low bits but the low bits are unaffected by the high bits.</li> </ul>
