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
