.
The data size of value to be displayed as the recurring decimal must be no
larger than 99 bytes. Each value
and the decimalpoint require
one byte,
and each digij of the
periodrequires
one byte. The following, for example,
would require
oltotal
of Bbytes (4 bytesfor the values, 1 byte for the decimal
point, 3 bytes for the period): 0.123

each
press of Ii!!iI will toggle the currently
displayed calculation result between its decimal fonn and fraction fonn.
Important:
.
Depending on the type of calculation resuttthat is on the display
when you press the Ii3i key, the conversion process may take some time
to perform.
.
With certain calculation results, pressing the
~
key will not
convert the displayed value.
.
When ON is selected for Rdec on the setup
menu, pressing
Ii3i
will switch the calculation resutt to recurring decimal fonn.
For details, see "Recurring Decimal Calculations'.
.
You cannot swijch from
decimal fonn to mixed fraction fonn if the total number of digits used in the
mixed fraction (including integer, numerator, denominator, and separator
symbols) is greater than 10.
Note: Wijh Natural Display (MathO), pressing
I!!!I
§) instead of §) after
inputting a calculation will display the calculation result in decimal fonn.
Pressing
Ii3i
after that will swijch the calculation resutt to recurring decimal
fonn, fraction fonn or n fonn. The
r
fonn of the result will not appear in
this case.
