[Chicken-users] currency-converter.egg

[Jean-Philippe Théberge]

In my process of learning "the chicken way" I have made an egg out of a
simple but useful currency converter.

[procedure] (currency-convert FROM TO AMOUNT #:table #:format?)

(currency-convert 'USD 'EUR 45.34)
=> "32.03"
(currency-convert 'USD 'EUR 45.34 #:format? #f)
=> 32.3003490774382
(currency-convert 'USD 'EUR 45.34 #:table '((EUR . 1)(USD . 34)))
=> "1.33"

Although it is nothing as sophisticated as most of the eggs, I though
someone might be interested.

Rates are fetched from the European Central Bank
