  4. If durationFormat.[[FractionalDigits]] is undefined, then
    a. Perform ! CreateDataPropertyOrThrow(nfOpts, "maximumFractionDigits", 9).
    b. Perform ! CreateDataPropertyOrThrow(nfOpts, "minimumFractionDigits", 0).
  5. Else,
    a. Perform ! CreateDataPropertyOrThrow(nfOpts, "maximumFractionDigits", durationFormat.[[FractionalDigits]]).
    b. Perform ! CreateDataPropertyOrThrow(nfOpts, "minimumFractionDigits", durationFormat.[[FractionalDigits]]).
