Keep in mind when inputting fractions on your calculator that the input procedure you need to use depends on whether natural display or linear display is selected as the display format (page 11), as shown below.

As you can see above, natural display lets you input fractions as they appear in your textbook, while linear display requires input of a special symbol ({).

Note

Under initial default settings, fractions are displayed as improper fractions.

Fraction calculation results are always reduced automatically before being displayed. Executing 2 { 4 =, for example, will display the result 1 { 2.
