4. While done is false, repeat for each row in Table 1 in order, except the header row:
...
j. If unit is "seconds", "milliseconds", or "microseconds", then
i. If unit is "seconds", then
1. Let nextStyle be durationFormat.[[MillisecondsStyle]].
...
iv. If nextStyle is "numeric", then
1. If unit is "seconds", then
a. Set value to value + duration.[[Milliseconds]] / 10^3 + duration.[[Microseconds]] / 10^6 + duration.[[Nanoseconds]] / 10^9.
...
l. If value is not 0 or display is not "auto", then
ii. If style is "2-digit" or "numeric", then
...
7. Let parts be ! PartitionNumberPattern(nf, value).
