Issue1914

Float formatting is broken in many non-English locales in Jython 2.7. It is a regression.

The last command prints "1,000000" instead of "1.000000":
$ export LC_ALL="pl_PL.UTF-8"
$ python2.5 -c 'print("%f" % 1.0)'
1.000000
$ python2.7 -c 'print("%f" % 1.0)'
1.000000
$ jython2.5 -c 'print("%f" % 1.0)'
1.000000
$ jython2.7 -c 'print("%f" % 1.0)'
1,000000
$

Arfrever: Do you know of a straightforward way to enable pl_PL.UTF-8 ?

I have tried working with locale-gen as described here: http://askubuntu.com/questions/76013/how-do-i-add-locale-to-ubuntu-server

but it doesn't seem to do the trick :(

BTW I always get this:

bash: warning: setlocale: LC_ALL: cannot change locale (pl_PL.UTF8)

OK got it reproduced - my next question: Is 1,00000 correct for pl_PL? In other words, is this a bug in our support of pl_PL or of compatibility with CPython?

For my near future TODO:

I can't apply this just now (working on something else) -- but the solution is simple - in PyString I need to do this:

-            template = new DecimalFormat("#,##0.#####");
+            template = new DecimalFormat("#,##0.#####", new DecimalFormatSymbols(java.util.Locale.US));

Fixed in default branch.
