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.
Example: log3 + '2 = 1.891334817
2'3 × 4 = 8'3
35'2 × 3 = 148.492424
(= 105'2)
150'2
= 8.485281374

2 × (3 – 2'5 ) = 6 – 4'5
23 × (5 – 2'3 ) = 35.32566285
(= 115 – 46'3 )
10'2 + 15 × 3'3 = 45'3 + 10'2
15 × (10'2 + 3'3 ) = 290.0743207
(= 45'3 + 150'2 )
'2 + '3 + '8 = '3 + 3'2
'2 + '3 + '6 = 5.595754113
