`cellsToLinkedMultiPolygon` bug on Apple Silicon #917

Open ajfriend opened 1 month ago

ajfriend commented 1 month ago

We have a bug computing cellsToLinkedMultiPolygon for the children of a pentagon which only seems to show up on Apple Silicon builds. I'm guessing this is a floating point issue?

Demonstrated in #916 .

Only on Apple Silicon, but not on x86: https://github.com/uber/h3/actions/runs/11062819778/job/30737940554?pr=916
