Modify Function 

18

Decimal calculation results are internally obtained in scientifi c 
notation, with up to 14 digits in the mantissa. However, since 
calculation results are displayed in the form designated by the 
display notation and the number of decimal places indicated, 
the internal calculation result may differ from that shown in the 
display. By using the modify function (

@

 

n

), the internal 

value is converted to match that of the display, so that the 
displayed value can be used without change in subsequent 
operations.

•  When using the WriteView editor, if the calculation result is 

displayed using fractions or irrational numbers, press 

U

 

to convert it to decimal form fi rst.

•  The modify function can be used in NORMAL, STAT, MATRIX, 

or LIST modes.

Simulation Calculation (ALGB) 

19

If you have to fi nd values consecutively using the same 
expression, such as plotting a curve line for 2

x

2

 + 1, or fi nding the 

variable values for 2

x

 + 2

y

 =14, once you enter the expression, 

all you have to do is to specify the value for the variable in the 
equation.

Usable variables: A–F, M, X and Y

•  Simulation calculations can only be executed in NORMAL 

mode.

•  Calculation ending instructions other than 

=

 cannot be 

used.

•  Variables and numerical values stored in the memories 

will be displayed in the variable entry screen. If you do 
not want to change any values, simply press 

e

.

•  Performing simulation calculation will cause values in 

memory to be overwritten with new values.

Solver Function 

20

The solver function fi nds the value for 

x

 that reduces the 

entered expression to zero.

•  This function uses Newton’s method to obtain an 

approximation. Depending on the function (e.g. periodic) or 
start value, an error may occur (ERROR 02) due to there 
being no convergence to the solution for the equation.

•  The value obtained by this function may include a margin of 

error. If it is larger than acceptable, recalculate the solution 
after changing the “Start” and 

d

x

 values.

•  Change the “Start” value (e.g. to a negative value) or 

d

x

 

value (e.g. to a smaller value) if:

•  no solution can be found (ERROR 02).

•  more than two solutions appear to be possible (e.g. a 

cubic equation).

•  to improve arithmetic precision.

•  The calculation result is automatically stored in the X memory.

accessed under the MATH menu, with a random number used as 
a normal distribution variable.

Notes:

•  P(t), Q(t), and R(t) will always take positive values, even when 

t < 0, because these functions follow the same principle used 
when solving for an area.

•  Values for P(t), Q(t), and R(t) are given to six decimal places.

arithmetic calculations (with the exception of division between 
matrices) and calculations that use 

x

3

x

2

, and 

x

1

. You can 

also use the following matrix-specifi c functions that are 
available in the MATH menu.

dim (

matrix name, row, column

)

Returns a matrix with dimensions 
changed as specifi ed.

fi ll (

value, row, column

)

Fills each element with a specifi ed 
value.

cumul 

matrix name

Returns the cumulative matrix.

aug (

matrix name, matrix name

) Appends the second matrix to the 

fi rst matrix as new columns. The fi rst 
and second matrices must have the 
same number of rows.

identity 

value

Returns the identity matrix with 
specifi ed value of rows and columns.

rnd_mat (

row, column

)

Returns a random matrix with 
specifi ed values of rows and columns.

det 

matrix name

Returns the determinant of a square 
matrix.

Calculation Ranges 

30

• 

Within the ranges specifi ed, this calculator is accurate to 

±

1 of the 10th digit of the mantissa. However, a calculation 

error increases in continuous calculations due to 
accumulation of each calculation error. (This is the same 
for 

y

x

x

r

, n!, e

x

, ln, Matrix/List calculations, etc., where 

continuous calculations are performed internally.)
Additionally, a calculation error will accumulate and 
become larger in the vicinity of infl ection points and 
singular points of functions.

• Calculation ranges

±

10

99

 to 

±

9.999999999 

×

 10

99

 and 0.

If the absolute value of an entry or a fi nal or intermediate 
result of a calculation is less than 10

99

, the value is 

considered to be 0 in calculations and in the display.

Display of results using 

r

Calculation results may be displayed using 

r

 when all of the 

following conditions are met:

•  When intermediate and fi nal calculation results are displayed 

in the following form:

±

a

P

b

e   

± 

c

P

d

f

•  When each coeffi cient falls into the following ranges:

 a 

<

 100; 1 

<

 b 

<

 1,000; 0 

 c 

<

 100;

 d 

<

 1,000; 1 

 e 

<

 100; 1 

 f 

<

 100

•  When the number of terms in the intermediate and fi nal 

calculation results is one or two.

Note:  The result of two fractional terms that include 

r

 will be 

reduced to a common denominator.

BATTERY REPLACEMENT

Notes on Battery Replacement

Improper handling of batteries can cause electrolyte leakage or 
explosion. Be sure to observe the following handling rules:

•  Make sure the new battery is the correct type.

•  When installing, orient the battery properly as indicated in the 

calculator.

•  The battery is factory-installed before shipment, and may 

be exhausted before it reaches the service life stated in the 
specifi cations.

Notes on erasure of memory contents

When the battery is replaced, the memory contents are erased. 
Erasure can also occur if the calculator is defective or when it 
is repaired. Make a note of all important memory contents in 
case accidental erasure occurs.

When to Replace the Battery

If the display has poor contrast or nothing appears on the display 
when 

j

 is pressed in dim lighting, even after adjusting the 

display contrast, it is time to replace the battery.

Cautions

•  An exhausted battery left in the calculator may leak and 

damage the calculator.

•  Fluid from a leaking battery accidentally entering an eye could 

result in serious injury. Should this occur, wash with clean 
water and immediately consult a doctor.

•  Should fl uid from a leaking battery come in contact with your 

skin or clothes, immediately wash with clean water.

•  If the product is not to be used for some time, to avoid damage 

to the unit from a leaking battery, remove it and store in a safe 
place.

•  Do not leave an exhausted battery inside the product.

•  Keep batteries out of the reach of children.

•  Explosion risk may be caused by incorrect handling.

•  Do not throw batteries into a fi re as they may explode.
