Grads 1N5(Gra)
(90˚ = π
2
radians = 100 grads)
A Specifying the Display Digits
To specify this display digit setting: Perform this key operation:
Number of Decimal Places
1N6(Fix)0(0) to 9(9)
Signifi cant Digits
1N7(Sci)1(1) to 9(9), 0(10)
Exponential Display Range
1N8(Norm) 1(Norm1) or
2(Norm2)
The following explains how calculation results are displayed in accordance with the setting
you specify.
• From zero to nine decimal places are displayed in accordance with the number of decimal
places (Fix) you specify. Calculation results are rounded off to the specifi ed number of
digits.
Example: 100 ÷ 7 = 14.286 (Fix = 3)
14.29 (Fix = 2)
• After you specify the number of signifi cant digits with Sci, calculation results are
displayed using the specifi ed number of signifi cant digits and 10 to the applicable power.
Calculation results are rounded off to the specifi ed number of digits.
Example: 1 ч 7 = 1.4286 Ч 10
–1
(Sci = 5)
1.429 × 10
–1
(Sci = 4)
• Selecting Norm1 or Norm2 causes the display to switch to exponential notation whenever
the result is within the ranges defi ned below.
Norm1: 10
–2
>
Ȋ x Ȋ , Ȋ x Ȋ > 10 10
Norm2: 10
–9
>
Ȋ x Ȋ, Ȋ x Ȋ > 10 10
Example: 100 ÷ 7 = 14.28571429 (Norm1 or Norm2)
1 ч 200 = 5. Ч 10
–3
(Norm1)
0.005 (Norm2)
