[jira] [Commented] (YUNIKORN-1896) TestCalculateAbsUsedCapacity() fails on ARM

["Wilfred Spiegelenburg (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YUNIKORN-1896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17750566#comment-17750566 ] 

Wilfred Spiegelenburg commented on YUNIKORN-1896:
-------------------------------------------------

The overflow detection works correctly the resulting value is however not consistent on different architectures.
ARM returns consistently an int64 with the same sign as the float64. Intel does a bit flip in some cases resulting in differences on the two platforms.
