esid: sec-Intl.DurationFormat.prototype.format
description: Checks that fractional milliseconds and microseconds are formatted correctly when microseconds or nanoseconds are the first units with "numeric" style.

PartitionDurationFormatPattern ( durationFormat, duration )
(...)
9.
(...)
g. If unit is "seconds", "milliseconds", or "microseconds", then
i. If unit is "seconds", then
1. Let nextStyle be durationFormat.[[MillisecondsStyle]].
ii. Else if unit is "milliseconds", then
1. Let nextStyle be durationFormat.[[MicrosecondsStyle]].
iii. Else,
1. Let nextStyle be durationFormat.[[NanosecondsStyle]].
iv. If nextStyle is "fractional", then
1. Set value to value + AddFractionalDigits(durationFormat, duration).
2. If durationFormat.[[FractionalDigits]] is undefined, then
a. Let maximumFractionDigits be 9𝔽.
b. Let minimumFractionDigits be +0𝔽.
3. Else,
a. Let maximumFractionDigits be 𝔽(durationFormat.[[FractionalDigits]]).
b. Let minimumFractionDigits be 𝔽(durationFormat.[[FractionalDigits]]).
4. Perform ! CreateDataPropertyOrThrow(nfOpts, "maximumFractionDigits", maximumFractionDigits ).
5. Perform ! CreateDataPropertyOrThrow(nfOpts, "minimumFractionDigits", minimumFractionDigits ).
6. Perform ! CreateDataPropertyOrThrow(nfOpts, "roundingMode", "trunc").
7. Set done to true.
