Added extra tests for the cases that @anba identified, in a fixup commit so it's easy to see what changed. I will squash it before merging. |

….hoursInDay The existing tests didn't cover some edge cases where implementations have to compute the exact result of `numerator / denominator`, where at least one of `numerator` and `denominator` can't be exactly represented by an IEEE-754 double precision floating point value. "precision-exact-mathematical-values-5.js" gets added in tc39#3961, so the new tests from this commit start at "precision-exact-mathematical-values-6.js".

Thanks for the review. Since yesterday I added some tests from @nicolo-ribaudo as well as some tests from @anba, which I've reviewed. So I think this is ready. I'll merge it at the same time as the proposal-temporal PR. |
Adapts or removes tests that relied on creating durations that are now out of range. Adds new tests for maximum in-range and minimum out-of-range durations.
NormalizedTimeDurationToDays can no longer loop indefinitely, because at a certain point we will hit the upper bound of MAX_SAFE_INTEGER, so rename the test to reflect that it can loop an arbitrary but limited number of times. Add a test for the RangeError condition in NormalizedTimeDurationToDays when the time zone calculates a day length that is not a safe integer number of nanoseconds. While editing these tests, rename them to match the current name of the AO and make sure the step numbers are up to date. (Normally I wouldn't care so much about that, but these tests can be pretty confusing so it's good to be able to refer to the spec text.)
