NAME

Lingua::SPA::Numeros - Translates numbers to spanish text

VERSION

version 0.0682

SYNOPSIS

   use Lingua::SPA::Numeros

   $obj = new Lingua::SPA::Numeros ('MAYUSCULAS' => 1)
   print $obj->Cardinal(124856), "\n";
   print $obj->Real(124856.531), "\n";
   $obj->{GENERO} = $FEMALE;
   print $obj->Ordinal(124856), "\n";

DESCRIPTION

Number 2 word conversion in SPA.

This module supports the translation of cardinal, ordinal and, real numbers, the module handles integer numbers up to vigintillions (that's 1e120), since Perl does not handle such numbers natively, numbers are kept as text strings because processing does not justify using bigint.

Currently Lingua::SPA::Numeros handles numbers up to 1e127-1 (999999 vigintillions).

METHODS

CONSTRUCTOR: new

To create a new Lingua::SPA::Numeros, use the new class method. This method can receive as parameters any of the above mentioned fields.

Examples:

      use Lingua::SPA::Numeros;
      
      # Use the fields' default values
      $obj = new Lingua::SPA::Numeros; 
      
      # Specifies the values of some of them
      $obj = Lingua::SPA::Numeros->new( ACENTOS => 0, 
                MAYUSCULAS => 1, GENERO => $FEMALE,
                DECIMAL => ',', SEPARADORES=> '"_' );
DECIMAL

Specifies the character string that will be used to separate the integer from the fractional part of the number to convert. The default value for DECIMAL is '.'

SEPARADORES

Character string including all of the format characters used when representing a number. All of the characters in this string will be ignored by the parser when analyzing the number. The default value for SEPARADORES is '_'

ACENTOS

Affects the way in which the generated string for the translated numbers is given; if it is false, the textual representation will not have any accented characters. The default value for this field is true (with accents).

MAYUSCULAS

If this is a true value, the textual representation of the number will be an uppercase character string. The default value for this field is false (lowercase).

HTML

If this is a true value, the textual representation of the number will be a HTML-valid string character (accents will be represented by their respective HTML entities). The default value is 0 (text).

GENERO

The gender of the numbers can be $MALE, $FEMALE or $NEUTRAL, respectively for femenine, masculine or neutral numbers. The default value is $MALE.

The following table shows the efect of GENDER on translation of Cardinal and Ordinal numbers:

 +---+---------------------+-----------------------------+
 | N |     CARDINAL        |          ORDINAL            |
 | u +------+------+-------+---------+---------+---------+
 | m | MALE |$FEMALE|$NEUTRAL|  $MALE   |  $FEMALE | $NEUTRAL |
 +---+------+------+-------+---------+---------+---------+
 | 1 | uno  | una  | un    | primero | primera | primer  |
 | 2 | dos  | dos  | dos   | segundo | segunda | segundo |
 | 3 | tres | tres | tres  | tercero | tercera | tercer  |
 +---+------+------+-------+---------+---------+---------+
SEXO

Deprecated option only for backward compatibility, use GENERO instead.

UNMIL

This field affects only the translation of cardinal numbers. When it is a true value, the number 1000 is translated to 'un mil' (one thousand), otherwise it is translated to the more colloquial 'mil' (thousand). The default value is 1.

NEGATIVO

Contains the character string with the text to which the negative sign (-) will be translated with. Defaults to 'menos'.

For example: default translation of -5 will yield "menos cinco".

POSITIVO

Contains the character string with the text to which the positive sign will be translated with. Defaults to ''.

For example: default translation of 5 will yield "cinco".

FORMATO

A character string specifying how the decimals of a real number are to be translated. Its default value is 'con %2d ctms.' (see the real method)

Aliases

By popular demand I have added the following aliases for the options:

    Alias        Natural Name

    ACCENTS       ACENTOS          
    UPPERCASE     MAYUSCULAS

cardinal

SYNOPSIS: $text = $obj->cardinal($num)

Parameters

$num

the number.

Description

Translates a cardinal number ($num) to spanish text, translation is performed according to the following object ($obj) settings: DECIMAL, SEPARADORES, SEXO, ACENTOS, MAYUSCULAS, POSITIVO and NEGATIVO.

This method ignores any fraction part of the number ($num).

Return Value

Textual representation of the number as a string

real

SYNOPSIS: $text = real($n; $genf, $genm)

Translates the real number ($n) to spanish text.

The optional $genf and $genm parameters are used to specify gender of the fraction part and fraction part magnitude in that order. If $genf is missing it will default to the GENDER option, and $genm will default to the $genf's value.

This translation is affected by the options: DECIMAL, SEPARADORES, GENDER, ACENTOS, MAYUSCULAS, POSITIVO, NEGATIVO and FORMATO.

Fraction format (FORMATO)

FORMAT option is a formatting string like printf, it is used to format the fractional part before appending it to the integer part. It has the following format specifiers:

%Ns

Formats the fractional part as text with precisión of N digits, for example: number '124.345' formated with string 'CON %s.' will yield the text 'ciento veinticuatro CON trescientas cuarenta y cinco milésimas', and formatted with string 'CON %2s.' will yield 'ciento veinticuatro CON treinta y cuatro centésimas'.

%Nd

Formats the fractional part as a number (no translation), with precision of N digits, veri similar to sprintf's %d format, for example: number '124.045' formated with 'CON %2d ctms.' will yield: 'ciento veinticuatro CON 04 ctms.'

ordinal

SYNOPSIS: $text = $obj->ordinal($num)

Parameters

$num

the number.

Description

Translates an ordinal number ($num) to spanish text, translation is performed according to the following object ($obj) settings: DECIMAL, SEPARADORES, GENERO, ACENTOS, MAYUSCULAS, POSITIVO and NEGATIVO.

This method croacks if $num <= 0 and carps if $num has a fractional part.

Return Value

Textual representation of the number as a string

Accessors

Each of the options has a setter/getter with the name of the option in lowercase, all the accessors have the following sintax:

Getters

  $obj->name_of_option()

Returns the current value of the option.

Setters

  $obj->name_of_option( $value )

Sets the option to $value and returns $obj
