Scientific calculation

Before performing the following calculation, check to see that your
calculator is fixed at 2 decimal places display format.

Reciprocal, Factorial

e – e = ?
[ 2ndF ] [ e

Fraction calculation

Fraction value display is as follow :
5 」 12
56 ⊔ 5 」 12
(Note) : Total of integer, numerator and denominator must be within 10
digits, or the fractional value couldn't be shown completely.
By pressing [ 2ndF ] [ → ], the displayed value will be converted to
d
