Converting
decimals to
fractions
To convert a decimal value to a fraction:
1. Set the number format mode to Fraction or Mixed
Fraction.
2. Either retrieve the value from the History, or enter the
value on the command line.
3. Press to convert the number to a fraction.
When converting a decimal to a fraction, keep the
following points in mind:
• When converting a recurring decimal to a fraction,
set the fraction precision to about 6, and ensure that
you include more than six decimal places in the
recurring decimal that you enter.
In this example, the
fraction precision is set
to 6. The top
calculation returns the
correct result. The
bottom one does not.
• To convert an exact decimal to a fraction, set the
fraction precision to at least two more than the
number of decimal places in the decimal.
