Using Engineering Notation
A simple key operation transforms a displayed value to engineering
notation.
Transform the value 1234 to engineering notation, shifting the
decimal point to the right.
1234 = 1234
W 1.234×10 3
W 1234×10 0
Transform the value 123 to engineering notation, shifting the decimal
point to the left.
123 = 123
1W(←) 0.123×10 3
1W(←) 0.000123×10 6
Calculation History
In the COMP, CMPLX, or BASE-N Mode, the calculator remembers up to
approximately 200 bytes of data for the newest calculation. 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.
