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 Fkey will not convert the displayed value. • 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 MathO, pressing 1=instead of =after inputting a calculation will display the calculation result in decimal form. Pressing F after that will switch to the fraction form or π form of the calculation result. The 'form of the result will not appear in this case.
