Statistics. The traditional calculator buttons allow you to enter data but not edit it. Entering data using the buttons is just a convenience for small data sets. The worksheets offer a more natural way to enter, edit and view data and to perform some common calculations. Worksheets are the primary user interface for statistics data, not the traditional calculator buttons. Fractions. The calculator allows you to directly enter fractions using two decimal points (.2.3 = 2/3, 1.2.3 = 1 2/3), convert to and from fractions, and when operating on a fraction the result is a fraction (2/3 * 5 = 10/3). You can switch between proper and improper forms (10/3 = 3 1/3). The display of a fraction is subject to a maximum denominator defined in the calculator’s settings. If an operation yields a fraction with a denominator larger than this max then a decimal value is shown. You can define this max (it is 99,999 by default) or you can turn it off.
