This result, 1.23E2, is the calculator’s version of powers-of-ten notation,

i.e., 1.235

. In this, so-called, scientific notation, the number 3 in

front of the Sci number format (shown earlier) represents the number of

significant figures after the decimal point. Scientific notation always

includes one integer figure as shown above. For this case, therefore, the

number of significant figures is four.

• Engineering format

The engineering format is very similar to the scientific format, except that

the powers of ten are multiples of three. To set this format, start by

pressing the H button. Next, use the down arrow key, ˜, to select

the option Number format. Press the

@CHOOSE

soft menu key (

), and

select the option Engineering with the arrow down key

. Keep the

number 3 in front of the Eng. (This number can be changed in the same

fashion that we changed the Fixed number of decimals in an earlier

example).

Press the !!@@OK#@ soft menu key return to the calculator display. The

number now is shown as:

Because this number has three figures in the integer part, it is shown with

four significative figures and a zero power of ten, while using the

Engineering format. For example, the number 0.00256, will be shown as:

1 2 ... 19 20 21 22 23 24 25 26 27 28 29 ... 174 175
