-// This masks the input with INT64_MAX, which removes the MSB; we then cast to an int64; the range is between 0 and INT64_MAX. We then use the MSB of the original value; if set, we negate the number, producing negative values for the upper half of the uint64 range. Note that we only need to check for hash -1 in this branch.
