Binary, octal, decimal, hexadecimal conversion and
calculations, as well as logical operations. Function
calculations and graph drawing cannot be performed.
3.SD mode
Standard deviation calculation (single-variable statistics).
4. LR mode
Regression calculation (paired-variable statistics).
With so many modes available, calculations should always
be performed after confirming which mode is active.
* IMPORTANT: When the power of the unit is switched off
(including Auto Power Off), the current system mode is
cancelled, and the unit will be set to the RUN mode when
switched on again. However, the calculation mode,
number of decimal place setting ( n), number
of significant digits( n), and angle unit (Deg,
Rad, Gra) will be retained in memory.
* To return to standard operation ( initialized state) press
(COMP mode) (RUN mode)
(Norm mode).
Number of input/output digits and calculation digits
• The allowable input/output range (number of digits) of this
unit is 10 digits for a mantissa and 2 digits for an
exponent. Calculations, however, are internally
performed with a range of 12 digits for a mantissa and 2
digits for an exponent.
3 x 10 5 ÷ 7 =
* Calculation results greater than 10 10 ( 10 billion) or less
than 10 -2 (0.01) are automatically displayed in exponential
form.
123456789 x 9638 =
Once a calculation is completed, the mantissa is rounded off to
* Calculations are performed in sequence, with the highest
priority operation first. Once a calculation is executed, it is
cleared from the stack.
Calculation modes
This unit features modes for manual calculations, storing
programs, and modes for general as well as statistical
calculations. The proper mode to suit calculational
requirements should be employed.
• Operation modes
There are a total of three operation modes.
1. RUN mode
Graph production as well as manual calculations and
program executions.
2. WRT mode
Program storage and editing.
3. PCL mode
Deletion of stored programs.
• Calculation modes
There are a total of six calculation modes which are
employed according to the type of calculation.
1. COMP mode
General calculations, including functional calculations.
2. BASE-N mode
