Convert numbers to words - their written form.
With npm:
npm install --save written-numberWith bower:

writtenNumber(1234); // => 'one thousand two hundred and thirty-four'
writtenNumber.defaults.lang = 'es';
writtenNumber(4758); // => 'cuatro mil setecientos cincuenta y ocho'
writtenNumber(1234, {lang: 'fr'}); // => 'mille deux cent trente-quatre'
writtenNumber(1234, {lang: 'es'}); // => 'mil doscientos treinta y cuatro'
writtenNumber(1234, {lang: 'az'}); // => 'min iki yüz otuz dörd'
writtenNumber(1234, {lang: 'pt'}); // => 'mil duzentos e trinta e quatro'
writtenNumber(1234, {lang: 'ar'}); // => 'ألف ومائتان وأربعة وثلاثون'

The separator is internationalized.lang- Could bestringorobject. Defaults to'en'. Determines which language to use. An i18n configuration object may be passed to support external language definitions.
Currently supported languages are:
| Language | lang |
|---|---|
| English | en |
| Portuguese (Brazil) | pt |
| Portuguese (Portugal) | ptPT |
| Spanish | es |
| French | fr |
| Esperanto | eo |
| Vietnamese | vi |
| Arabic | ar |
| Azerbaijan | az |
| Turkish | tr |
| English (Indian) | enIndian |
| Ukrainian | uk |
| Indonesian | id |
| Russian | ru |
Each language has its own unique grammar exceptions. You can create your own language.json file in the folder "i18n" and give writtenNumber support for it. I don't think the current scheme and logic cover all the cases, but may be cover some.
The following parameters have been used for the currently available languages:
| Parameter | Type | Description | Examples |
|---|---|---|---|
useLongScale |
boolean | Indicates if it uses long or short scale. | This differs the meaning of the words billion, trillion and so on. |
baseSeparator |
string | Separates the base cardinal numbers. | 29 -> twenty-eight. Spanish uses the connector " y " |
unitSeparator |
string | Separates the units from the last base cardinal numbers. | 1234 -> one thousand two hundred and thirty-four |
allSeparator |
string | Separates all cardinals, not only the last one. | 1125 -> ألف ومائة وخمسة وعشرون |
base |
Object | Base cardinals numbers. Numbers that have unique names and are used to build others. | |
alternativeBase |
Object | Alternative versions of base cardinals numbers for usage with specific units. These bases will be treated as an extension for the default base. |
"alternativeBase": { "feminine": {"1":"одна","2":"дві"} } |
units |
Array | A list of number units (string or Object). Gives support to singular, dual an plural units. Check the Object parameters below. | |
unitExceptions |
Object | Sometimes grammar exceptions affect the base cardinal joined to the unit. You can set specific exceptions to any base cardinal number. | Converting 1232000 in Spanish: Without Exception (Wrong): -> uno millón doscientos treinta y dos mil With Exception: -> un millón doscientos treinta y dos mil |
A unit can be:
- A simple string. e.g.
"hundred" - An Object with multiple parameters:
| Unit parameter | Description | e.g. of languages |
|---|---|---|
singular |
One element. | All |
dual |
Two elements. | ar |
plural |
Two or more elements. (or 3 or more) | All |
few |
Between 2 and 4 including. | uk |
useAlternativeBase |
Overwrites default base. |
uk |
useBaseInstead |
Use the base cardinal number instead. | es,hu,pt |
useBaseException |
Specify with which unit (1 to 9) you don't want to use the base, and instead use the regular behavior. | es,hu,pt |
avoidPrefixException |
Units not using the base cardinal number prefix for unit 1. | id,tr,it |
avoidInNumberPlural |
Units not using the plural form with trailing numbers other than 0. | fr |
restrictedPlural |
Plural only for 3 to 10. Singular if >= 11. | ar |
useSingularEnding |
Use singular form for numbers ending with 1. | uk |
useFewEnding |
Use few form for numbers ending with 2, 3 or 4. | uk |
avoidEndingRules |
Plural form used instead of useSingularEnding and useFewEnding |
uk |
Do your changes and submit a PR. If you've write access and want to bump the version, run mversion [major|minor|patch] -m. That'll bump both bower.json and package.json.
