=head1 NAME
HTML::FormFu::Deflator::FormatNumber - Format a number for a locale
=head1 VERSION
version 2.07
=head1 SYNOPSIS
    locale: de_DE
    elements:
      - type: Text
        name: number
        deflators:
          - type: FormatNumber
            precision: 4
      - type: Text
        name: price
        deflators:
          - type: FormatNumber
            precision: 2
            trailing_zeroes: 1
    # "123456.22" will be rendered to "123.456,22" (german locale)
=head2 locale
If no locale is found, the server's locale will be used.
This method is a special 'inherited accessor', which means it can be set on
the form, a enclosing block element, the field, or this filter.
When the value is read, if no value is defined it automatically traverses
the element's hierarchy of parents, through any block elements and up to the
form, searching for a defined value.
