Example:
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
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.
a' b
' is the least common multiple of
c
•
• Since calculation results are reduced to a common denominator,
they are displayed in ' form even if coefficients (
are outside the corresponding ranges of coefficients (
' 3
Example:
11
• 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.
