I am testing the library and I cannot convert quantities with decimals. For example 150.2 and I can't convert amounts like 0.69 to euros either.

Can you tell me how to do these conversions?

Hello!
Thank you very much for implementing this API! I use it and would like to have some small improvement:
Since the xml file is currently fetched on every request, I would like to store it for some hours until I will fetch it again.

As an inspiration, you could do the same like https://github.com/simplepie/simplepie. The file cache would be enough for me right now. This is how they implemented it:

https://github.com/simplepie/simplepie/blob/master/tests/CacheTest.php#L95-L100

PS: Please also tag the current state as I can only require dev-master via composer. Thanx!

Hi, first of all, thank you for the API. I run into one issue today. (worked perfectly before)

URL to XML with daily rates should be changed to https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml

Old URL with http returns status 301 and script doesnt work...

Hi!
It would be nice if I could fetch the exchange rate on a specific date in the past.

// e.g. 
$date = new \DateTime('2020-10-01');
echo $converter->toEuro(150, 'USD', 3, $date);

I wonder if there is a way to change the base currency from EUR to lets say BGN, e.g. USD -> BGN; CZK ->BGN, etc. Thank you!

When there is an cULR error it cannot be handled because curl handler ($ch) is closed before error message is extacted:
in ECB.php:
}

    curl_close($ch);

    throw new ECBException(curl_error($ch), ECBException::DATA_DOWNLOAD_FAILED);
