■ Exponential Displays
The display can show calculation results only up to 10 digits long. When an intermediate
value or a final result is longer, the calculator automatically switches over to exponential
notation. Values greater than 9,999,999,999 are always displayed exponentially, while the
lower limit is selectable. Note the following:
Type Lower limit
Upper limit
A (Norm 1) 0.01 (10
2)
9,999,999,999 (1010)
B (Norm 2)
0.000000001 (10 9 ) 9,999,999,999 (10w)
Values less than the lower limits or greater than the upper limit shown above are displayed
using exponential format.
Use the following procedure to switch between the Type A lower limit and the Type B low-
er limit:
I Check the display to see if the FIX or SCI symbols are shown, indicating that the num-
ber of significant digits or the number of decimal places have been specified. If either
of the symbols is shown, press
