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.
π
: The following are the
π
forms that are supported.
This is true only in the case of Math format.
n

( n is an integer.)
c
d π

(depending on fraction display format
setting)
• 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.
