Function Calculations

Use the key to enter the COMP Mode when you want to perform
function calculations.
Note: Using functions can slow down a calculation, which may delay
display of the result. Do not perform any subsequent operation while
waiting for the calculation result to appear. To interrupt an ongoing
calculation before its result appears, press
Pi (π), Natural Logarithm Base e
π is displayed as 3.141592654, but π = 3.14159265358980 is used for
internal calculations.
e is displayed as 2.718281828, but e = 2.71828182845904 is used for
internal calculations.

Trigonometric Functions

Specify the angle unit before performing calculations.
Example 1: sin 30° = 0.5 (LineIO) (Angle unit: Deg)
-1
Example 2: sin 0.5 = 30° (LineIO) (Angle unit: Deg)

Hyperbolic Functions

Input a function from the menu that appears when you press
The angle unit setting does not affect calculations.
Example 1: sinh 1 = 1.175201194
