[jira] Updated: (HARMONY-3655) [drlvm][helpers] All JITs and
interpreter perform incorrect floating point division when dividend is -0.0
[ https://issues.apache.org/jira/browse/HARMONY-3655?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gregory Shimansky updated HARMONY-3655:
---------------------------------------
Summary: [drlvm][helpers] All JITs and interpreter perform incorrect floating point division when dividend is -0.0 (was: [drlvm]All JITs and interpreter perform incorrect floating point division when dividend is -0.0)

> Key: HARMONY-3655
> URL: https://issues.apache.org/jira/browse/HARMONY-3655
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: Mikhail Fursov
>
> For the test below:
> public class Hello {
> static float a=0f, b=-1f, c=1f, d=-0f;
> public static void main(String[] args) {
> float res;
> res = ((a * b) % c);
> System.out.println("res="+res);
>
> res = d % c;
> System.out.println("res="+res);
> }
> }
> The same problem we have for 'double' type
> RI output is:
> res=-0.0
> res=-0.0
> When JET/OPT/Interpreter print:
> res=0.0
> res=0.0
> I think that the problem is with VM helper.
