• Math format causes fractions, irrational numbers, and other

expressions to be displayed as they are written on paper.

• Linear format causes fractions and other expressions to be

displayed in a single line.

Calculation Result Display Examples

• Fix: The value you specify (from 0 to 9) controls the number of

decimal places for displayed calculation results. Calculation results
are rounded off to the specified digit before being displayed.
Example: 100 

÷

 7 = 14.286 (Fix3)

14.29   (Fix2)

• Sci: The value you specify (from 1 to 10) controls the number of

significant digits for displayed calculation results. Calculation results
are rounded off to the specified digit before being displayed.
Example: 1 

÷

 7 = 1.4286

• Norm: Selecting one of the two available settings (Norm1, Norm2)

determines the range in which results will be displayed in non-
exponential format. Outside the specified range, results are
displayed using exponential format.
