write-int

npm version

Convert integer numbers to their written form.

Inspired by js-written-number

Usage

Install with npm

npm install --save write-int

And require it where needed:

var writeInt = require('write-int');

Reference as script

It also works to simply reference in a script tag:

<script src="path/to/writeInt.min.js"></script>

English

English is the default language. Numbers supported between -1e66 and 1e66 exclusive (1 followed by 66 zeros or 1 * 10^66).

writeInt(123);// => 'one hundred and twenty-three'
 
writeInt(123, {lang: 'en'});// => 'one hundred and twenty-three'

Spanish

Numbers supported between -1e24 and 1e24 (exclusive).

writeInt(2030, {lang: 'es'});// => 'dos mil treinta'

German

Numbers supported between -1e18 and 1e18 (exclusive).

writeInt(2000, {lang: 'de'});// => 'zweitausend'

Esperanto

Numbers supported from 0 up through 1e15 - 1.

writeInt(1234, {lang: 'eo'});// => 'mil ducent tridek kvar'

Lojban

Numbers supported between -1.8e308 and 1.8e308 (exclusive).

writeInt(11, {lang: 'jb'});// => 'papa'

Specification

writeInt(number[, options])

  • @param {number|string} number
  • @param {object} [options]
  • @property {string} [options.lang='en']
  • @property {boolean} [options.einhundert=false]
    • whether to include 'ein' for 100 in German
    • 100 is 'einhundert' if true, 'hundert' if false
  • @property {boolean} [options.eintausend=false]
    • whether to include 'ein' for 1000 in German
    • 1000 is 'eintausend' if true, 'tausend' if false
  • @returns {string|null}

Returns number written out if it is representable (within supported range of valid language), else returns null. If number is type string, it should be a base 10 number.

Example:

writeInt(11);// => 'eleven'
writeInt("11");// => 'eleven'
 
writeInt(1e2);// => 'one hundred'
writeInt("1e2");// => 'one hundred'
 
writeInt(11, {lang: 'es'});// => 'once'
 
writeInt(100, {lang: 'de'});// => 'hundert'
writeInt(100, {lang: 'de', einhundert: true});// => 'einhundert'
 
writeInt();// => null
writeInt({});// => null
writeInt("a");// => null
writeInt('foo');// => null

writeInt.supported(lang)

  • @param {string} lang
  • @returns {boolean}

Returns whether lang is a supported language.

Example:

writeInt.supported('en');// => true
 
writeInt.supported('xy');// => false

writeInt.representable(number, lang)

  • @param {number|string} number
  • @param {string} lang
  • @returns {boolean}

Returns whether number is representable (within the supported range) in lang. Returns false if lang is not supported. If writeInt() is called for an unrepresentable number, then null is returned.

Example:

writeInt.representable(12, 'en');// => true
 
writeInt.representable(12, 'xy');// => false
 
writeInt.representable('a', 'en');// => false

Supported languages

  • English lang: 'en'
  • Spanish lang: 'es'
  • German lang: 'de'
  • Esperanto lang: 'eo'
  • Lojban lang: 'jb'

Adding a language

  1. Create a copy of src/languages/interface.js and rename it to the ISO 639-1 code of the language.
  2. Implement the functions and properties for the language. Any helper functions and properties can be made as well.
  3. Create a test file in test with the same file name.

Note: Lojban does not have a ISO 639-1 code. "jb", which is unspecified in ISO 639-1, is used for Lojban. (The Lojban code in ISO 639-2 and ISO 639-3 is "jbo").
