Example:
The underlined areas in the above examples indicate what caused
decimal form to be used.
Reasons why the results of the examples are displayed in
decimal form
- Value outside of the allowable range
- More than two terms in the calculation result
• Calculation results displayed in
'
form are reduced to a common
denominator.
•
c
′
is the least common multiple of
c
and
f
.
• Since calculation results are reduced to a common denominator,
they are displayed in
'
form even if coefficients (
a
′
,
c
′
, and
d
′
)
are outside the corresponding ranges of coefficients (
a
,
c
, and
d
).
Example:
• The result is displayed in decimal form even when any intermediate
result has three or more terms.
Example: (1 +
'
2 +
'
3 )(1 –
'
2 –
'
3 )(= –4 – 2
'
6 )
= –8.898979486
• If a term is encountered during the calculation cannot be displayed
as a root (
'
) form or a fraction, the calculation result is displayed
in decimal form.
