Lingua::FR::Numbers - Converts numeric values into their French string equivalents


 # Procedural Style
 use Lingua::FR::Numbers qw(number_to_fr ordinate_to_fr);
 print number_to_fr( 345 );

 my $vingt  = ordinate_to_fr( 20 );
 print "Tintin est reporter au petit $vingt";

 # OO Style
 use Lingua::FR::Numbers;
 my $number = Lingua::FR::Numbers->new( 123 );
 print $number->get_string;
 print $number->get_ordinate;

 my $other_number = Lingua::FR::Numbers->new;
 $other_number->parse( 7340 );
 $french_string = $other_number->get_string;


This module converts a number into a French cardinal or ordinal. It supports decimal numbers, but this feature is experimental.

The interface tries to conform to the one defined in Lingua::EN::Number, though this module does not provide any parse() method. Also, unlike Lingua::En::Numbers, you can use this module in a procedural manner by importing the number_to_fr() function.

If you plan to use this module with greater numbers (>10e20), you can use the Math::BigInt module:

 use Math::BigInt;
 use Lingua::FR::Numbers qw( number_to_fr );

 my $big_num = new Math::BigInt '1.23e68';
 print number_to_fr($big_num);
 # cent vingt-trois quintillions de sextillions

This module should output strings for numbers up to, but not including, 1e75, but due to a lack of documentation in French grammar, it can only reliably output strings for numbers lower than 1e51. For example, 1e72 is 'un sextillion de sextillion', but I am unable to say 1e51 or 1e69, at least for now.



number_to_fr( $number )

 use Lingua::FR::Numbers qw(number_to_fr);
 my $depth = number_to_fr( 20_000 );
 my $year  = number_to_fr( 1870 );
 print "Jules Vernes écrivit _$depth lieues sous les mers_ en $year.";

This function can be exported by the module.

ordinate_to_fr( $number )

 use Lingua::FR::Numbers qw(ordinate_to_fr);
 my $twenty  = ordinate_to_fr( 20 );
 print "Tintin est reporter au petit $twenty";

This function can be exported by the module.


new( [ $number ] )

 my $start = Lingua::FR::Numbers->new( 500 );
 my $end   = Lingua::FR::Numbers->new( 3000 );
 print "Nous partîmes ", $start->get_string, 
       "; mais par un prompt renfort\n",
       "Nous nous vîmes ", $end->get_string," en arrivant au port"

Creates and initializes a new instance of an object.

parse( $number )

Initializes (or reinitializes) the instance.


 my $string = $number->get_string;

Returns the number as a formatted string in French, lowercased.


 my $string = $number->get_ordinate;

Returns the ordinal representation of the number as a formatted string in French, lowercased.


Invalid number format: '$number'

(W) The number specified is not in a valid numeric format.

Number '$number' too big to be represented as string

(W) The number is too big to be converted into a string. Numbers must be lower than 1e75-1.

Though the module should be able to convert big numbers (up to 10**36), I do not know how Perl handles them.
