wangxiyuan commented on FLINK-15505:
------------------------------------
[~fly_in_gis]
1.8.3 doesn't contain my change, for example:
[https://github.com/apache/flink/blob/release-1.8.3/flink-table/flink-table-planner/src/main/scala/org/apache/flink/table/plan/cost/DataSetCost.scala#L112]
I guess my change is not released now?
the test failure on ppc64le is the same with aarch64. So use StrictMath can
solve this problem.
I just wrote a test :
[https://github.com/wangxiyuan/test_diff_arch/blob/master/TestMath.java]
the test result on diff arch:
[https://travis-ci.com/wangxiyuan/test_diff_arch/builds/144255686]
You can see that StrichMath does the same behavior on different arch.
[~redmark-ibm] Please try flink master branch for these two tests or wait
another new release IMO.
