Angle Unit Conversion
The calculator default angle unit setting is "Degree". If you need to
change into "Radian" or "Gradient", you can press a number of
times until you reach the setup screen:
Then press the corresponding number key , , or for the
angle unit you need. Then the display will show the
D
,
R
, or
G
indicator accordingly.
To convert an angle unit between "Degree", "Radian" and "Gradient",
you can press DRG and the following display menu will be
shown:
Then, press , , or will convert the displayed value into the
selected angle unit. If you want to indicate the value with other degree
unit after conversion, change the unit using .
