1.2.3 Exponential display
During normal calculation, this unit is capable of displaying up to 10 digits. Values that exceed this limit,
however, are automatically displayed in exponential format. You can choose between 2 different types of
exponential display formats.
-2
(0.01) >x, x ≥ 10
NORM 1 mode : 10
-9
(0.000000001) >x, x≥ 10
NORM 2 mode : 10
Selection of these modes can be carried out by pressing
been made for the number of decimal places or significant digits. The present status is not displayed, so it
is necessary to perform the following procedure to specify either display format:
÷
1 200
EXE
(All of the examples in this manual show calculation results using the NORM 1 mode.)
How to interpret exponential format ?
11
1.2 indicates that the result is equivalent to 1.2x10
point in 1.2 eleven places to the right. Since the exponent is positive. This results in the value
120,000,000,000.
