k Converting an Input Value to the
Calculator's Default Angle Unit
After inputting a value, press 1G(DRG') to display the angle
unit specification menu shown below. Press the number key that
corresponds to the angle unit of the input value. The calculator will
automatically convert it to the calculator's default angle unit.
Example: To convert the following values to degrees:
π

The following procedure assumes that the calculator's default angle
unit is degrees.

k Exponential Functions and Logarithmic
Functions
• Exponential and logarithmic functions can be used in the same
modes as the trigonometric functions.
• For the logarithmic function "log(", you can specify base
the syntax "log (
If you input only a single value, a base of 10 is used for the
calculation.
• "ln(" is a natural logarithm function with base
• You can also use the & key when inputting an expression with
the form of "logm
