SCalculation Result Display Range with Π

A calculation results is displayed using Π format in the following cases.

•When the calculation result can be displayed in the form nΠ n is an integer up to 106.

bb

•When the calculation result can be displayed in the form a c Π or c Π

However, {number of a digits + number of b digits + number of c digits} must be 9 or less

b b

when the above a c or c is reduced.*1*2 Also, the maximum number of allowable c digits is three.*2

*1 When c < b, the number of a, b, and c digits are counted when the fraction is converted from an improper fraction ( bc ) to a mixed fraction (a bc ).

*2 When “Manual” is specified for the Setup screen “Simplify” setting, the calculation result may be displayed in decimal format, even if these conditions are met.
