About Calculation Errors
An error indicator appears on the display and further calculation becomes impossible whenever an
error occurs.
Any of the following conditions produces an error.
•
Whenever the number of digits in the mantissa of an intermediate or final result exceeds 12
•
Whenever the number of digits in the mantissa of a value in calculator memory exceeds 12
digits. In this case, the unit automatically retains the previous value stored.
•
Division by zero
•
Attempting to calculate the square root of a negative value
To clear an error
Tap
C
to clear an error and continue with the same calculation from the point immediately before
the error occurred.
To clear the entire calculation and start again, tap
AC
.
To perform constant calculations
1. On the calculator screen, input the first value of the operation, tap an arithmetic operator key
twice, and then input the second value of the operation.
•
You can perform a constant calculation using
!
,
@
,
#
, or
$
.
•
The first value you input (the one to the left of the arithmetic operator) is the one that will be
used as the constant.
•
Tapping an arithmetic operator key twice causes the indicator K to appear on the display to
indicate that a constant calculation is being performed.
2. Tap = to display the result of the operation.
•
Inputting 4
#
#
2
=
would produce a result of 8.
3. Tap
=
again to multiply the result by the constant.
•
Tapping
=
again with the example shown under step 2 would produce a result of 32 (8
#
4).
•
Each subsequent tap of
=
multiplies the last result obtained by the constant. Continuing with
the above example, tapping
=
would produce the following results:
=
128 (32
#
4),
=
512
(128
#
4),
=
2048 (512
#
4), and so on.
To correct entries during calculations
•
If you enter a wrong value, tap
C
to clear the value and then input the correct one.
•
If you tap the wrong arithmetic key (
!
,
@
,
#
, or
$
), simply tap the correct arithmetic key
before inputting anything else.
