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).

a	π or	b	π (depending on fraction format setting).
--		a--
b		c

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 → Decimal
