notation.

Transform the value 1234 to engineering notation, shifting the

decimal point to the right.

1234 =

1234

W 1.234×10

W 1234×10

Transform the value 123 to engineering notation, shifting the decimal

point to the left.

123 =

1W( ← ) 0.123×10

1W( ← ) 0.000123×10

Calculation History

In the COMP, CMPLX, or BASE-N Mode, you can scroll through calculation

history contents using f and c.

1 + 1 = 2 1 + 1 = 2

2 + 2 = 4 2 + 2 = 4

3 + 3 = 6 3 + 3 = 6

(Scrolls back.) f 4

(Scrolls back again.) f 2

Note: Calculation history data is all cleared whenever you press O, when

you change to a different calculation mode, when you change the display

format, or whenever you perform any reset operation.

Replay

While a calculation result is on the display, you can press d or e to edit

the expression you used for the previous calculation.

4 × 3 + 2.5 = 14.5 b 4 * 3 + 2.5 = 14.5

4 × 3 − 7.1 = 4.9 (Continuing) dYYYY- 7.1 = 4.9

Note: If you want to edit a calculation when the ' indicator is on the right

side of a calculation result display (see “Reading the Display”), press A

and then use d and e to scroll the calculation.
