PayPal 5.3.2 Invalid request - see details

[Derbai]

I am not able to let Paypal module work. I get the following error:

Currency amount must be non-negative number, may optionally contain exactly 2 decimal places separated by '.', optional thousands separator ',', limited to 7 digits before the decimal point and currency which is a valid ISO Currency Code

The call is:

``` stdClass Object ( [transactions] => Array ( [0] => stdClass Object ( [amount] => stdClass Object ( [total] => 174.79 [currency] => EUR [details] => Array ( [shipping] => 7.00 [tax] => 29.98 [subtotal] => 136.27 [handling_fee] => 1.54 )

Can someone help me on fix it? Thansk, Daniele

I just fixed it: on function createPaymentObject I replaced round() with number_format() and it solved the problem.

[Derbai]

To fix the same problem is needed also the following fix: on modules/paypal/classes/PayPalRestApi.php

$details['shipping_discount'] = abs(round($remaining - $giftWithoutTax, 2));

need to be changed as follow:

$details['shippingdiscount'] = numberformat(abs($remaining - $giftWithoutTax), 2);

Was this fixed in 5.3.3? I am getting the same error
