Press MENU, then press 1 to select the RUN-MAT screen. Press CTRL SET UP. Navigate to Display. For basic work, we recommend that Display be set to Normal.
However, if you want numbers displayed to a fixed number of places past the decimal point, then press F1 to select Fix. In response to the prompt, press a number between 0 and 9 to fix that many places past the decimal point.
For example, to have numbers displayed and rounded to 6 digits past the decimal point, press 6 EXE. Press EXE again to return to the RUN-MAT home screen. The screen at right displays the resulting answers for 19/8 and for the square root of 17 with the fix 6 option.
