Hi, Brian.

This looks fantastic.

The changes in Formatter look fine to me.

I also took a quick look at FormattedFloatingDecimal and am thrilled. I think you changes have also addressed this bug:

5057835- FormattedFloatingDecimal: massive code duplication in J2SE http://bugs.sun.com/view_bug.do?bug_id=5057835

I think you're good to go once you verify that you successfully ran the regression tests in test/java/util/Formatter.

Thanks! iris

I would like to see the real world-class experts on this scary math stuff (Alan Eliasen, Tim Buktu) be made honorary jdk reviewers, just for their area of specialization, if that was bureaucratically possible. Shouldn't the original authors be cc'ed?

The code is awesome. My thorough review found only these defects:

Use third person in the first sentence of a javadoc - e.g. s/Retrieve/Retrieves/.

Don't use the denigrated C style char zero[] = Instead use char[] zero =

This looks odd:

normalized as a//binary*

The original comment looked more normal:

normalized as a binary

Otherwise, approved!
