Rounding in Pressero

The Pressero system uses the "Banker's rounding" approach for rounding dollar amounts.  This is also known as the half-to-even rounding approach.  As an example, if the total taxes on an order came to $9.235, Pressero would round this to $9.24.  However, if the total taxes were $9.245 would also be rounded to $9.24.  Please see this article for further explanation:  This is generally considered the best rounding system for money.
