Fractions can be converted to decimal values and vice versa.
*
2
When the total number of characters, including integer, numerator, denominator and delimiter
marks in an intermediate or final calculation result exceeds 10, the fraction is automatically
displayed in decimal format. (10-digit example: 1{1{123456)
*
3
Calculations containing both fractions and decimals are calculated in decimal format.
• Pressing the !f*(
<
) key toggles the display fraction between mixed fraction and
improper fraction format.
