Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

First reported with PHP 5.3, the last comment is about 5.5. ICU version producing the issue stays
however within the same version range. Today PHP 5.5+ with ICU 51.2+ shows no issues. This brings to
the conclusion, that the issue doesn't lay on PHP. Rougly same ICU (or maybe just data) version
range produces the issue. For what matters, I've added ext/intl/tests/bug53735.phpt with all
the snippets from this ticket.

Thanks.

PHP Version 5.5.29-1
ICU version 4.4.1

$fmt = new \NumberFormatter("de_DE", \NumberFormatter::DECIMAL);
$fmt->format(23.25);

Returns NaN

I can reproduce this with PHP 5.3.10 on Ubuntu 12.04 64.
It is strange for me, because running from CLI works as expected.

Code to run:
$f = new NumberFormatter('hu_HU', NumberFormatter::PERCENT, '#,##0%');
echo $f->format(0.26) . "\n";

Get always NaN with NumberFormatter::ORDINAL if the current local is not en_US.

PHP 5.3.3
ICU lib 4.4.1-8
OS Debian Squeeze
