[jira] Updated: (HARMONY-6268) [classlib][luni] Math.min fails when
comparing doubles and floats with the same values
[ https://issues.apache.org/jira/browse/HARMONY-6268?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tim Ellison updated HARMONY-6268:
---------------------------------
Summary: [classlib][luni] Math.min fails when comparing doubles and floats with the same values (was: Math.min fails when comparing doubles and floats with the same values )
> [classlib][luni] Math.min fails when comparing doubles and floats with the same values
> ---------------------------------------------------------------------------------------

> Key: HARMONY-6268
> URL: https://issues.apache.org/jira/browse/HARMONY-6268
> Project: Harmony
> Issue Type: Bug
> Components: Classlib
> Environment: all
> Reporter: Catherine Hope
> Assignee: Tim Ellison
>
> Math.min always returns "-0.0" when comparing doubles and floats of the same value. This is a regression since revision 788021 "Minor optimization suggested by Ian on HARMONY-6242 (Math.max(double, double) gives wrong answer when Math.max(-0.0d, 0.0d))".
> testcase:
> assertEquals(1.0, Math.min( 1.0 , 1.0 )); // gives expected:<1.0> but was:<-0.0>
> assertEquals(1.0f, Math.min( 1.0f , 1.0f )); // again, gives expected:<1.0> but was:<-0.0>
> Math.max doesn't fail in this way.
