Eshop calculates incorrectly

Hello,
I have the following problem:
The price for the product that I record should include VAT and must be stated as such on the shop page.
So if I specify 119.00 euros, the shop page must say “119.00 euros incl. VAT”. When I go to the shopping cart, the price must be 100.00 euros and 19% VAT = 19.00 euros.
But the shop calculates incorrectly.
The shop page says 110.23 ??
Entered 119.00!!!
The shopping cart will then contain 92.63 ?? without VAT.
And 19% VAT 17.60???

No matter what settings I make, I never get the right result!!

Best regards
Ralf

Dear Ralf,

The reason because you have wrong exchanged rate of currency. I resolved the problem and replied to you via ticket system.
