k Exponential Display
The calculator normally displays values up to 10 digits long. Values that exceed this
limit are automatically converted to and displayed in exponential format. You can
specify one of two different ranges for automatic changeover to exponential display.
Norm 1 ........... 10
–2
(0.01) > |x|, |x| > 10
10
Norm 2 ........... 10
–9
(0.000000001) > |x|, |x| > 10
10
uTo change the exponential display range
1. Press !Z to display the Set Up Screen.
2. Use f and c to move the highlighting to “Display”.
3. Press 3 (Norm).
The exponential display range switches between Norm 1 and Norm 2 each time you
perform the above operation. There is no display indicator to show you which expo-
nential display range is currently in effect, but you can always check it by seeing
what results the following calculation produces.
Ab/caaw
(Norm 1)
(Norm 2)
All of the examples in this manual show calculation results using Norm 1.
uHow to interpret exponential format
1.2E+12 indicates that the result is equivalent to 1.2 × 10
12
. This means that you
should move the decimal point in 1.2 twelve places to the right, because the expo-
nent is positive. This results in the value 1,200,000,000,000.
1.2E–03 indicates that the result is equivalent to 1.2 × 10
–3
. This means that you
should move the decimal point in 1.2 three places to the left, because the exponent
is negative. This results in the value 0.0012.
