How I round Shippiong cost which is calculated with 24% tax?

Rule:
Name=Rahtiluokka 2; MaxLength<3; Shipping=28.225806;

This makes 35.01 €. My customer wants it 35.00€.

How I can round?

It seems that in that webhotel only 3 digits means something, not 6.

EDITED: Is solution ShippingWithTax=35.00

My used version AdvancedShippingRules says that "ShippingWithTax variable is unknown"...

Dear Sutinse,
Which version of the plugin do you use?
The latest version at demo.open-tools.net seems to work fine with ShippingWithTax...

Best regards,
Reinhold
