Re: [Openexr-devel] ImathTest Failure

[Florian Kainz]

Looks like the test that failed previously passes now, but the next test
fails for a similar reason.  Try changing line 100 in testExtractEuler.cpp
to

        if (abs (D[j][k]) > 0.000002)

I wonder if the compiler generates calls to a "fast but sloppy" version
of the functions defined in math.h.  Does your compiler have some kind
of "fast vs. accurate" option?
