I wrote those tests to make sure we have consistent (bit-identical)
results for various floating point functions across different Croquet
VMs. How these tests ended up in 3.9 I have no idea - they are part of
Croquet, for sure, and in the context of Croquet they make perfect sense
(and they pass if you use a Croquet VM and they fail if you don't -
which is exactly what they should do).
To me, it points out more a problem with the selection of code being put
into the base image rather than any failing of the test itself. The test
is meaningful in the context it was designed for.
