• Testing
  • Are there new or updated unit or integration tests?
  • Do the tests cover the happy paths?
  • Do the tests cover the unhappy paths?
  • Are there an adequate number of fuzz tests to ensure that we are
    covering the full input space?
  • If matching Solidity behavior, are there differential fuzz tests that
    ensure that Rust matches Solidity?

any idea as to why this started happening?

I think 1e11 (aka correct up to the 8th decimal) is pretty reasonable given that the spot price itself is an approximation of the realized price for a non-infinitesimal trade size.

That being said, AFAIK this was not failing before the latest flurry of activity in the rust part of the repo. I'm going to approve to unblock other PRs from landing with this failing, but I think we should keep it in mind in case we start seeing more failures.

Because the test added in the flurry #919

I absorbed this PR into #938 so that we could have both fixes in one PR and CI would pass. Closing this PR.
