Angle Unit Conversion
°,
r
,
g
: These functions specify the angle unit. ° specifies degrees,
r
radians, and
g
grads.
Input a function from the menu that appears when you perform the
following key operation: (DRG ).
Example: π/2 radians = 90°, 50 grads = 45° (Angle unit: Deg)
(π) 2 (DRG ) (
r
)
90
50
(DRG ) (
g
) 45
Exponential Functions
Note that the input method is dif
ferent depending upon whether you are
using Natural Display or Linear Display.

Logarithmic Functions
Use the key to input log
a
b as log (a,b).
Base 10 is the default setting if you do not input anything for a.
The
key also can be used for input, but only while Natural Display is
selected. In this case, you must input a value for the base.
Example 1: log

1000 = log 1000 = 3
1000 3
Example 2:
