Fraction Calculations
How you should input fractions depends on the input/output
format that is currently selected.
• Default settings display fractions as improper fractions.
• Fraction calculation results are always reduced before
being displayed.
Example:
(Fraction format a b/c)
• Mixed fraction input is possible only when “a b/c” is
specified for the fraction format.
• In MATH mode, press
(
) to input mixed fractions.
• If the total number of digits used for a mixed fraction
(including integer, numerator, denominator, and separator
symbols) is greater than 10, the value is automatically
displayed in decimal format.
• The result of a calculation that involves both fraction and
decimal values is displayed in decimal format.
