Using S-D Transformation
You can use S-D transformation to transform a value between
its decimal (D) form and its standard (S) form (fraction,
π
).
Formats Supported for S-D Transformation
S-D transformation can be used to transform a displayed
decimal calculation result to one of the forms described below.
Performing S-D transformation again converts back to the
original decimal value.
Note: When you transform from decimal form to standard
form, the calculator automatically decides the standard form
to use. You cannot specify the standard form.
Fraction: The current fraction format setting determines whether the
result is an improper fraction or mixed fraction.
π
:
The following are the
π
forms that are supported. This is true
only in the case of Math format. n
π
(n is an integer).
π
or
π
(depending on fraction format setting).
Transformation to a fractional
π
form is limited to inverse
trigonometric function result and values that are normally
expressed in radians.
After obtaining a calculation result in form, you can convert
it to decimal form by pressing the key. When the original
calculation result is in decimal form, it cannot be converted
into form.
Examples of S-D Transformation
Note that S-D transformation can take some time to perform.
Example: Fraction

Each press of the key toggles between the two forms.
