3rd digit for tax calculations needed!

Hi Sambapos3 developer and community,

this is not so much a question, it's rather a suggestion: In good old new York City a 4.5% sales tax, a 4.0 NY State Sales and Use Tax and a 4% and a Metropolitan Commuter Transportation District surcharge of 0.375% are charged for items sold in restaurants. This gives a combined tax rate of 8.875%. The tax templates in Sambapos3 only allow a two digit value, e.g. 8.87% or 8.88%. Of course the difference isn't a big one, but for a total sum of a 400$ family meal, the 0.005% difference makes up for 2 cents that we either do not correcly charge or overcharge, depending on whether we use 8.88% or 8.87%. Could you please allow 3 digit tax values after the comma? The problem is not so much the difference itself, we can easily pay for that, it's rather that some customers actually complained about the tax not being calculated correcly after they checked the bill.

Kind regards, Klaas
