Bhaskara

A library to convert numbers in full to actual numbers

Bhaskara is a small library that aims to convert written numbers in real integers for programming purposes, providing an easy interface for extending your own languages.

Install

$ npm install --save-dev bhaskara

Usage

var bhaskara = require('bhaskara');

bhaskara('zero'); // 0
bhaskara('ten'); // 10
bhaskara('one hundred eighty-nine'); // 189
bhaskara('forty-two million and one'); // 42000001
bhaskara('twenty-two trillion ninety-two'); // 22000000000092
bhaskara('a duck'); // NaN, because a duck is not a number

CLI

If installed globally, you can use bhaskara as a command line utility, for instance:

$ bhaskara --locale en forty-two
$ 42

Available locales: en, pt.

Configuration

The function takes three arguments with the format bhaskara(number, [locale, [mapper]]).

number

Type: string

The number in full to be converted.

locale

Type: json or string Default: 'en'

locale should be either a json object with the main translations for the language, for instance, "twenty": 20; or a string, representing a built-in language.

mapper

Type: function Arguments: number : number

A function that takes a number as parameter and must return either an array of numbers or a number. This function aims to filter the numbers after being translated. This function must ensure that no number is a composition of a power of ten, i.e. every number must be in the range [0-9] or be a base 10^x.

If no mapper is given and there is no default mapper for the locale provided, then the identity function is used.
