Convert numbers to words - their written form.
With npm:
npm install --save @freddydrodev/written-number
With bower:
bower install @freddydrodev/written-number
import { WrittenNumber } from "written-number";
import { EN, Es } from "written-number/i18n";
const Converter = new WrittenNumber({ language: EN });
Converter.convert(1234); // => 'one thousand two hundred and thirty-four'
Converter.setOptions({ language: Es });
Converter.convert(4758); // => 'cuatro mil setecientos cincuenta y ocho'

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"

. That'll bump both bower.json
and package.json
.
