Fixed betting odds parser and formatter. Supports decimal, fractional and moneyline/american style odds.
Installation
npm install odds --save
Usage
var odds = require('odds');
odds(5, 2).format('decimal'); // "3.50"
odds(100).format('moneyline'); // "+10,000"
Parsing
Odds default to "0/1" and may be passed in as strings or numbers.
As parameters:
odds(num, [den]);
As an array:
odds([num, den]);
As an object:
odds({num: num, den: den});
As a string:
odds('2/3');
odds('+10,000');
odds('2.50');
Formating
Defaults to decimal if a format type is not specified.
Types:
- american (alias)
- decimal
- fractional
- moneyline
Methods
config({opts}) - Get or set configuration options.
frac({num, den}) - Get or set the fractional odds.
num(num) - Get or set the odds numerator.
den(num) - Get or set the odds denominator.
parse(val) - Parse options or string to set the odds.

Global Settings
You may configure options globally. If your data always represents odds as an object with numerator/denumerator properties then configure the library to use those properties by default. e.x:
var Odds = require('odds');
var odds = odds
.global()
.config({num: 'numerator'})
.config({den: 'denominator'});
var data1 = {numerator: 2, denominator: 3};
var data2 = {numerator: 4, denominator: 1};
odds(data1).format('fractional'); // "2/3"
odds(data2).format('fractional'); // "4/1"
