Toggling Calculation Results

While Natural Display is selected, each press of f will toggle the currently
displayed calculation result between its fraction form and decimal form, its
' form and decimal form, or its π form and decimal form.
π ÷ 6 = 1
6
15( π ) / 6 =
( ' 2 + 2) × ' 3 = ' 6 + 2 ' 3 = 5.913591358
(! 2 e+ 2 )*! 3 = '
While Linear Display is selected, each press of f will toggle the currently
displayed calculation result between its decimal form and fraction form.
1 ÷ 5 = 0.2 = 1
1 / 5 =
1 – 4 = 1
5 5
1 - 4 ' 5 =
Important: • Depending on the type of calculation result that is on the display
when you press the f key, the conversion process may take some time
to perform. • With certain calculation results, pressing the f key will not
convert the displayed value. • When ON is selected for Rdec on the setup
menu, pressing f will switch the calculation result to recurring decimal form.
For details, see "Recurring Decimal Calculations". • You cannot switch from
decimal form to mixed fraction form if the total number of digits used in the
mixed fraction (including integer, numerator, denominator, and separator
symbols) is greater than 10.
Note: With Natural Display (MathO), pressing 1= instead of = after
inputting a calculation will display the calculation result in decimal form.
Pressing f after that will switch the calculation result to recurring decimal
form, fraction form or π form. The ' form of the result will not appear in
this case.

you are using Natural Display or Linear Display.
