Fractions can be converted to decimal values and vice versa.
*
2
When the total number of characters, including integer, numerator, denominator and delimiter
marks exceeds 10, the fraction is automatically displayed in decimal format.
*
3
Calculations containing both fractions and decimals are calculated in decimal format.
• Pressing the !M(
<
) key toggles the display fraction between mixed fraction and
improper fraction format.
