Transforming Displayed Values
You can use procedures in this section to transform a
displayed value to engineering notation, or to
transform between standard form and decimal form.
Using Engineering Notation
k simple key operation transforms a displayed value
to engineering notation.
Transform the value 1,234 to engineering notation
shifting the decimal point to the right.

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, n).
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.
It: The following are the n forms that are
supported.
This is true only in the case of Math format
n It (n is an integer.)
^jiorcF^ii (depending on fraction format
setting)
•Transformation to a fractional »form is limited to
inverse trigonometric function result and values
that are normally expressed in radians.
---------------------------------------- 41-----------------------------------------
After obtaining a calculation result in form,
you can convert it to decimal form by pressing
the rsiig 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.
