Fun with EDD; showing EUR price in USD (and vice versa)

I was playing around with Easy Digital Downloads (because this) and I choose EUR as currency, but I wanted the price to be also displayed in USD. Obviously there’s a premium add-on for that, but as I don’t want to purchase stuff just yet, I concocted an alternative myself. Here’s the resulting snippet of code that shows the price in USD for shops with EUR currency and shows the price in EUR when the shop is in USD;

add_action("plugins_loaded","edd_curconv_init");
function edd_curconv_init() {
	$curpos = edd_get_option( 'currency_position', 'before' );
	$curcur = strtolower(edd_get_currency());
  	if (in_array($curcur, array("eur","usd"))) {
	  $filtername="edd_".$curcur."_currency_filter_".$curpos;
	  add_filter($filtername, "edd_eur_dollar_conv",10,3);
	}
}

function edd_eur_dollar_conv($formatted, $currency, $price) {
  $rate=1.13;
  if ($currency === "EUR") {
	$outprice = $price * $rate;
	$outrate = "USD";
  } else if ($currency === "USD") {
	$outprice = $price / $rate;
	$outrate = "EUR";
  }
  
  if (!empty($outprice)) {
	$out = " ( ~ ".edd_currency_filter(round($outprice,2),$outrate).")";
	$formatted.=$out;
  }
  
  return $formatted;
}

This obviously lacks the features and robustness of that Currency Converter add-on, so (don’t) use (unless) at your own risk.
