Transforming Displayed
Values
You can use the procedures in this section to transform a displayed
value to engineering notation, or to transform between standard form
and decimal form.
k Using Engineering Notation
A simple key operation transforms a displayed value to engineering
notation.
Appendix
<#035> Transform the value 1,234 to engineering notation, shifting
the decimal point to the right.
<#036> Transform the value 123 to engineering notation, shifting
the decimal point to the left.
k 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 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
π
( n is an integer.)
c
d π
or
c
b π
a
(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.
