Note
• If the total number of elements (integer + numerator + denominator + separator symbols)
of a fraction calculation result is greater than 10 digits, the result will be displayed in
decimal format.
• If an input calculation includes a mixture of fraction and decimal values, the result will be
displayed in decimal format.
• You can input integers only for the elements of a fraction. Inputting non-integers will
produce a decimal format result.
