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.
n
π (n is an integer.)
d
c
π or a
b
c
π (depending on fraction display format setting)
Example 1: √
2 + √8 = 3√2 (MathI/MathO)
2 8
2 8 (≈)
Example 2: sin(60) =
√3
2
(MathI/MathO) (Angle Unit: Degree)
60
Example 3: sin
-1
(0.5) =
1
6
π
(MathI/MathO) (Angle Unit: Radian)
23
