First of all, everything works as expected. The 34s behaves exactly as other classic HPs. So everything is fine here.

I assume you want to calculate 19% VAT from a net value. ;-)
That's trivial:

12
[ENTER]
65
[x]
19
[%]

The percent function keeps the base value in Y and replaces X with the 19% tax amount.
So you end up with 780 in Y and 148,20 in X.
Now you can add the tax with a simple [+] to get 928,20.

BTW you do not need this 0 FILL at the beginning. You only work with the numbers you entered, so there is no need to clear anything before.
