I'm using Number::Format to format values in a template as in the docs:
[% USE Number.Format %]
[% num | format_number %]
Number::Format will use POSIX to determine the current locale -- as does
Perl. What appears to be happening is "num" above is getting rendered as
a string causing a "isn't numeric" warning in Number::Format. (See below)
My question is should the filter get the stringified version of the number?
I tried the (num + 0) trick but that didn't work.
One fix is this:
[%
USE formatter = Number.format;
formatter.format_number( num, 2, 2 );
%]
The problem is I'm using Number::Format widely and using the filter form,
so by calling setlocale() I'll be generating a lot of warnings -- and
getting invalid results.
Here's output from the script below. Note how the .79 got dropped in the
value formatted within the template.
------------- [fr_FR] ------
Rendered in Perl.
Number is [123456,789] and formatted is [123456,79]
-- calling ->process
Argument "123456,789" isn't numeric in numeric comparison (<=>) at
/Users/bill/perl5/perlbrew/perls/perl-5.16.1/lib/site_perl/5.16.1/Number/Format.pm
line 541.
Rendered in Template:
Lang is 'fr_FR' and fetched locale 'fr_FR'
Number is '123456,789' => '123456
And the script:

use warnings;
use Template;
use POSIX;
use Number::Format;
my $template = <<'EOF';
[% USE Number.Format %]
Rendered in Template:
Lang is '[% cur_lang %]' and fetched locale '[% locale %]'
Number is '[% num %]' => '[% num | format_number %]
EOF

my $locale = setlocale( &LC_ALL, $cur_lang );
my $formatter = Number::Format->new;
my $num_formatted = $formatter->format_number( $num );
warn "\n------------- [$cur_lang] ------\n\n";
warn "Rendered in Perl.\n Number is [$num] and formatted is

warn "\n -- calling ->process \n\n";
my %stash = (
cur_lang => $cur_lang,

);
$tt->process( \$template, \%stash )

}
