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

To 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
exponential 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.

How to interpret exponential format
1.2
E
+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
exponent is positive. This results in the value 1,200,000,000,000.
1.2
E
–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.
