Great

Hi, this is great, solved my issue on Metical (Mozambique)to be avaiable on store (instead of adding code on fuctions.php of my theme folder, this is a more elagant way and also convert to my Paypal USD payments.

Meanwhile I found a bug on code on conversion.
When I try to do payment (store in Metical), it converts to USD using the conversion rate propely but Paypal returns this error:

“The link you have used to enter the PayPal system contains an incorrectly formatted item amount.”

But it is a simple trick to fix this. Thus paypal only accept amounts with 2 decimal places. So you can correct you code with a round function as per below:

***FIX:
On file woocommerce-custom-currencies/woocommerce-custom-currencies.php, go to function apply_conversion( $paypal_args ) {

Replace from:

$paypal_args[ $key ] = $value * floatval( $conversion_rate );

to:
$paypal_args[ $key ] = round($value * floatval( $conversion_rate ),2);

That’s it ??
