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 display format setting determines

whether the result is an improper fraction or mixed
fraction.

The following are the

forms that are supported.

This is true only in the case of Math format.

(

is an integer.)

(depending on fraction display format
setting)

• Transformation to a fractional

form is limited to inverse

trigonometric function results 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 to

form.

Examples of S-D Transformation

Note that S-D transformation can take some time to perform.

Example:

• Each press of the

key toggles between the two forms.
