Entering the VAT rate when submitting an offer

Which options do I have to consider when entering the VAT rate (Value Added Tax rate) when submitting an offer?

When submitting offers, hotels and service providers can enter the VAT rate for each offered service in the corresponding field next to the price.

The VAT rate is entered without entering a comma, please use the english spelling, e.g. 7.0 (a dot instead of a comma!). The entry of numbers after the dot is allowed e.g. 10.5. Please note that the entered value is not checked, the input field is not subject to validation. The entry consists of the numerical input without percentage (%) characters.
