3Fix 4Norm Specifies the number of digits for display of a calculation
result.
Fix: The value you specify (from 0 to 9) controls the number of decimal
places for displayed calculation results. Calculation results are rounded off
to the specified digit before being displayed.
Example:
L 100 ÷ 7 = 14.286 (Fix 3)
14.29 (Fix 2)
Norm: Selecting one of the two available settings (Norm 1, Norm 2)
determines the range in which results will be displayed in non-exponential
format. Outside the specified range, results are displayed using exponential
format.

5ab/c 6 d/c Specifies either mixed fraction (ab/c) or improper fraction
(d/c) for display of fractions in calculation results.
7Simp 1Auto ; 2Manual Specifies automatic or manual simplification
of fractions. When manual is specified, fraction calculation results are always
displayed as improper fractions, even if the fraction display format setting is
ab/c.
Even if the result of a calculation can be displayed as a fraction when
automatic simplification is used, performing the same calculation with manual
simplification may produce a non-fraction (decimal) result.
