Displaying Calculation Results
in a Form that Includes
'
2,
π
,
etc.
(Irrational Number Form)
When “MthIO” is selected for the input/output format, you can specify
whether calculation results should be displayed in a form that includes
expressions like
'
2 and
π
(irrational number form).
• Pressing
=
after inputting a calculation displays the result using
irrational number form.
• Pressing
1
=
after inputting a calculation displays the result
using decimal values.
Note
• When “LineIO” is selected for the input/output format, calculation
results are always displayed using decimal values (no irrational
number form) regardless of whether you press
=
or
1
=
.
•
π
form (form that includes
π
within irrational number display) display
conditions are the same as those for S-D conversion. For details,
see “Using S-D Transformation”.
