•Transformation to a fractional π 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 f 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: Fraction → Decimal
