This partially works, but it's very finicky and unpolished.
For example without specifying an amount, "usd to euro" works, while "usd to eur" doesn't, even though both are valid currency codes.
Also, when it does work on my examples, there is not a lot of usefulness in the result. It literally says = euro0.97 (euros)
. So, little precision, no historical values, etc. It seems to be relying on Wolfram Alpha which is somewhat bizarre for currency exchange.
