Fraction calculation

Fraction value display is as follow :

5 」 12

56 ⊔ 5 」 12

Display of 125

Display of 56 125

(Note) : Total of integer, numerator and denominator must be within 10 digits, or the fractional value couldn’t be shown completely.

By pressing [ 2ndF ] [ → d e ], the displayed value will be converted to

the improper fraction.
