     [ https://issues.apache.org/jira/browse/HARMONY-6486?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pons Rudy updated HARMONY-6486:
-------------------------------

    Attachment: 6486-java6.patch

A patch for the java6 branch. It only calls DecimalFormat.setRoundingMode(RoundingMode.HALF_UP), and add regression tests.
Working on a java5 patch, but java5 don't have DecimalFormat.setRoundingMode.

> Formatter use DecimalFormat to format numbers, with the default rounding mode (RoundingMode.HALF_EVEN) instead of RoundingMode.HALF_UP, ie System.out.printf("%.1f", 0.25); will print 0.2 instead of 0.3.
