Specifying the Number of Significant Digits

This specification is used to automatically round intermediate results and final results to the number of digits you have specified.

As with the number of decimal places, displayed results are rounded to the specified number of digits, but stored results are normally not rounded.

To specify the number of significant digits (Sci.), select [SCI] in the sub-menu "FIX/SCI/NORM" and then you are asked to enter a value indicating the number of significant digits (0~9) as below.

Sci 0~9?

Note : "0" indicating 10 significant digits.

Meanwhile, the "Sci" indicator will appear on the display.

Shifting the Decimal Place

You can use the key [ENG] to shift the decimal point of the displayed value three places to the left or right. Each 3-place shift to the left is the same as dividing the value by 1000, and each shift to the right is the same as multiplying by 1000. This means that this function is useful when converting metric weights and measures to other metric units.

Memory

This calculator contains 9 standard memories. There are two basic types of memories, i.e., "variable" memories, which are accessed by using the [STO] and [RCL] keys in combination with the alphabets A, B, C, D, E, F, M, X and Y. The "independent" memory, which is accessed by using the [M+] , [Shift] [M–]and [RCL] and [M] keys. The independent memory uses the same memory area as variable M.

Contents of both the variable and independent memories are protected even when the power is turned OFF.

Variable memories

Up to 9 values can be retained in memory at the same time, and can be recalled when desired.

To clear memory contents, press [0] [STO] [M].

Addition/subtraction to or from sum in memory cannot be carried out with [M+], [SHIFT] [M–] keys in "SD" mode and "REG" mode.

Difference between [STO][M] and [M+], [SHIFT][M–] :- Both [STO] [M] and [M+], [SHIFT] [M–] can be used to input results into memory, however when the [STO] [M] operation is used, previous memory contents are cleared. When either [M+] or [SHIFT] [M–] is used, value is added or subtracted to or from present sum in memory.

Example: Input 456 into memory "M" using [STO] [M] procedure. Memory already contains value of 123.

Special Functions

Answer Function

This unit has an answer function that stores the result of the most recent calculation. Once a numeric value or numeric expression is entered and [=] is pressed, the result is stored by this function.

To recall the stored value, press the [Ans] [=] key. When [Ans] is pressed, "Ans" will appear on the display, and the value can be used in subsequent calculations.

Example: 123456 = 579
789579 = 210
[ON/AC][1][2][3][][4][5][6][=]	123+456	579.
		D
[7][8][9][][Ans]	789–Ans_ 579.
		D
[=]	789–Ans
		210.
		D

Numeric values with 12 digits for a mantissa and 2 digits for an exponent can be stored in the "Ans" memory. The "Ans" memory is not erased even if the power of the unit is turned OFF. Each time [=] , [Shift] [%] , [M+] , [Shift] [M–] , and [STO]  ( = A ~ F, M, X, Y ) is pressed, the value in the Ans memory is replaced with the new value produced by the calculation execution. When execution of a calculation results in an error, however, the "Ans" memory retains its current value.

Note:- Contents of "Ans" memory are not altered when RCL  ( = A~F, M, X, Y) is used to recall contents of variable memory. Also, contents of "Ans" memory are not altered when variables are input when the variable input prompt is displayed.
