Press the !!@@OK#@ soft menu key to complete the selection:

Press the !!@@OK#@ soft menu key return to the calculator display. The number now is shown as:

Notice how the number is rounded, not truncated. Thus, the number 123.4567890123456, for this setting, is displayed as 123.457, and not as 123.456 because the digit after 6 is > 5.

•Scientific format

To set this format, start by pressing the H button. Next, use the down arrow key, ˜, to select the option Number format. Press the @CHOOS soft menu key ( B), and select the option Scientific with the arrow down key ˜. Keep the number 3 in front of the Sci. (This number can be changed in the same fashion that we changed the Fixed number of decimals in the example above).

Press the !!@@OK#@ soft menu key return to the calculator display. The number now is shown as:
