OC 3.0.2.0 / PayPal Exp Checkout / Round problem ! Help

Hello,

I don't understand why, but sometimes, there is a difference of 0,01€ or a bit more, bewteen the Opencart order, and the final Payment by PayPal.
An recent exemple : Opencart announce 45,40€, but in PayPal, he paid 45,39€.

What's wrong exactly ? am I alone with this problem ? Is paypal calculating different from PayPal ?

Thanks for your help !

/edit : got a concrete exemple !

Why Opencart is showning a bad price ?? The good price should be 45,39€, how paypal is able to have the good price while Opencart is sending the bad one ?

Can it being related to this problem ?

Maybe this will help you

Hello,

Thanks for your answer, in fact, the problem is finally not related to Paypal. I saw it because Paypal calculate the right amount instead of Opencart !!

Please, have a look to this exemple in video. Here, we can see the round problem if we pass a number of articles. If we have 47 items, round is OK. If we have 48 items, round is totally f$*ù$ed up..

Find the video here.

I am able to reproduce more specifically the problem :

If a add 130 items with 5.5% of taxe with a price of 5€ ==> everything is fine
If a add 129 items with 5.5% of taxe with a price of 5€ ==> 0.1cents is missing on final price
If a add 129 (and more) items with 20% of taxe with a price of 5€ ==> everything is fine
If a add 129 items (and more) with 5.5% of taxe with a price of 6€ (and more or less) ==> everything is fine

What's wrong ?? This problem occured on each items which are in this case. It seem to be related to price and taxe.
