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.
