Hi,

I found a random BUG that came from PHP. In function is_full_payment_through_wallet() you make comparison between a float (cart total) and a string (wallet balance) without formatting them. In some case, the same value in both of them don’t give true on ($current_wallet_balance >= $total) comparison, but something like -1.7763568394003E-15 for example.

I suggest this in your next update :

number_format ((float)woo_wallet()->wallet->get_wallet_balance( get_current_user_id(), ‘edit’ ), 2);
in replacement of :
woo_wallet()->wallet->get_wallet_balance( get_current_user_id(), ‘edit’ ); // Line 253

$total = number_format ((float) $order->get_total(), 2);
in replacement of:
$total = (float) $order->get_total(); // Line 262

$total = number_format ((float) get_woowallet_cart_total(), 2);
in replacement of:
$total = (float) get_woowallet_cart_total(); // Line 266

For the moment, I use your filter is_valid_payment_through_wallet to make this correction.
