Displaying Calculation Results in a Form that Includes √2, π, etc. (Irrational Number Form)

While MathI/MathO is selected for Input/Output on the setup menu, 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 (≈) after inputting a calculation displays the result using decimal values.


Note

When MathI/DecimalO or LineI/DecimalO is selected for Input/Output on the setup menu, calculation results are always displayed using decimal values (no irrational number form) regardless of whether you press or (≈).

The following are the π forms that are supported.
nπ (n is an integer.) dcπ or abcπ (depending on fraction display format setting)


Example 1:2 + √8 = 3√2 (MathI/MathO)

  • 28
  • 28(≈)

Example 2: sin(60) = 3 2  (MathI/MathO) (Angle Unit: Degree)

  • 60

Example 3: sin-1(0.5) = 16π (MathI/MathO) (Angle Unit: Radian)

  • (sin-1) 0.5
