Random Numbers
A pseudo-random number with three significant digits can be gen-
erated by pressing @ ` =.
To generate the next random number, press =.
This function can be performed in the normal and statistics modes.
(This function is not supported under the N-Base function.)
• Random numbers use memory Y. Each random number is gen-
erated on the basis of the value stored in memory Y (pseudo-
random number series).
• To generate a new series of pseudo-random numbers, press
N O Y to clear the memory Y.

Selecting the Display Notation and Decimal Places
The calculator has four display notation systems for displaying
calculation results. When FIX, SCI, or ENG symbol is displayed,
the number of decimal places can be set to any value between 0
and 9. Displayed values will be reduced to the corresponding
number of digits.

• If the value for floating point system does not fit in the following
range, the calculator will display the result using scientific notation
system:

Determination of the Angular Unit
In this calculator, the following three angular units can be speci-
fied.
DEG (°)

SCIENTIFIC CALCULATIONS
• Press m 0 to select the normal mode.
• In each example, press N to clear the display.
• If the FIX, SCI, or ENG indicator is displayed, clear the indicator
by pressing @ f.

[Temporary memories (A-D, X and Y)]
A stored value can be recalled as a value or variable to be used in
equations.
• In case an infinite decimal is stored in the memory, it can be
recalled as a variable to obtain accurate answers.
Ex.) 1 / 3 O Y (0.3333...is stored to Y)
3 * R Y =
0.999999999
3 * @ K Y =
1.
[Independent memory (M)]
In addition to all the features of temporary memories, a value can
be added to or subtracted from an existing memory value.
Press N O M to clear the independent memory.
[Last answer memory (ANS)]
The calculation result obtained by pressing = or any other
calculation ending instruction is automatically stored in the last
answer memory.
Note:
Calculation results of the functions indicated below are automati-
cally stored in memories X or Y; preexisting contents of X or Y will
be overwritten.
• Random numbers .................. Y memory
• →rθ, →xy ............................... X memory, Y memory
Temporary memories and last answer memory are cleared even
when the same mode is reselected.
