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. Norm 1: 10-2 Ͼ |x|, |x| м 1010 Norm 2: 10-9 Ͼ |x|, |x| м 1010 Example: L 1 ÷ 200 = 5 × 10-3 (Norm 1) 0.005 (Norm 2) 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. Example: 2 2 3 × 5 1 8 sh(Simp)b(Auto) k 2 e 2 c 3 e*k 5 e 1 c 8 = ­ 41 3 sh(Simp)c(Manual) 328 k 2 e 2 c 3 e*k 5 e 1 c 8 = ­ 24 8]CONT' Adjusts display contrast.
