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”.

Example 1: '2 +'8 = 3'2
