# Convertator
A simple currency converter which can use different sources to fetch rates and provides a rack-like middleware feature.
[](https://badge.fury.io/rb/convertator)
## Usage
**Simple example**
```ruby
require 'convertator/converter'
converter = Convertator::Converter.new
converter.convert(100, :USD, :RUB)
=> 0.55e4
converter.convert_digits(100, :USD, :RUB)
=> "5500.0"
```
**Multi convertion**
```ruby
Convertator::Converter.new(:static).convert_multi_s(100, :GBP, [:AMD, :RUB, :GBP])
=> ["47.12398", "3336.69827", "100.0"]
```
**Define accuracy and handler**
```ruby
Convertator::Converter.new(:static, 7)
```
**Use file cache middleware**
```ruby
irb(main):002:0> require 'convertator/middlewares/file_cache_middleware'
=> true
irb(main):003:0> converter = Convertator::Converter.new do |c|
irb(main):004:1* c.add Convertator::Middlewares::FileCacheMiddleware.new('/tmp/convertator.cache')
irb(main):005:1> end
=> #
converter.convert_s(100, :GBP, :RUB)
=> 7000.0
```
