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

Norm 2 ........... 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

exponential display range is currently in effect, but you can always check it by

seeing what results the following calculation produces.

Ab/caaw

All of the examples in this manual show calculation results using Norm 1.

uHow to interpret exponential format

+12 indicates that the result is equivalent to 1.2 × 10

1.2

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.

–03 indicates that the result is equivalent to 1.2 × 10

1.2

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.

(0.01) > |x|, |x| > 10

–2

(0.000000001) > |x|, |x| > 10
