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)

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:
