## README

## What's mongoose-float?
[![npm version](https://badge.fury.io/js/mongoose-float.svg)](https://www.npmjs.com/package/mongoose-float)

This library can solve one well known problem with JavaScript Number arithmetic imprecise, when, for example, 3.3 * 3 becomes 9.899999999999999, ugly.
This can occur when you try to save double values in Mongo DB, it can be balance, discounts etc.

#### Getting start
```
npm install mongoose-float
```

#### Basic usage
```javascript
var mongoose = require('mongoose');
var Float = require('mongoose-float').loadType(mongoose);

var UserSchema = mongoose.Schema({ balance: { type: Float } });
var User = mongoose.model('User', UserSchema);

var user = new User({ balance: 100.111111111 });

// Output: user.balance = 100.11
```


#### Specify the count of fractional digits
```javascript
var mongoose = require('mongoose');
var Float = require('mongoose-float').loadType(mongoose, 4);

var ProductSchema = mongoose.Schema({ price: { type: Float } });
var Product = mongoose.model('Product', ProductSchema);

var product = new Product({ price: 200.222222222 });

// Output: product.price = 200.2222
```
