u Angle Units, Coordinate Conversion, Sexagesimal Operations (ANGL)
[OPTN] - [ANGL]
• { ° } / { r } / { g } ... {degrees}/{radians}/{grads} for a specific input value
• { ° ’ ” } ... {specifies degrees (hours), minutes, seconds when inputting a degrees/minutes/
seconds value}
• {
° ’ ”
} ... {converts decimal value to degrees/minutes/seconds value}
• The {
° ’ ”
} menu operation is available only when there is a calculation result on the display.
• { Pol( } / { Rec( } ... {rectangular-to-polar}/{polar-to-rectangular} coordinate conversion
• { 'DMS } ... {converts decimal value to sexagesimal value}
u Engineering Symbol (ESYM) [OPTN] - [ESYM]
• { m } / {
 } / { n } / { p } / { f } ... {milli (10

)}
• { ENG } / { ENG } ... shifts the decimal place of the displayed value three digits to the {left}/{right}
and {decreases}/{increases} the exponent by three.
When you are using engineering notation, the engineering symbol is also changed
accordingly.
• The {ENG} and {ENG} menu operations are available only when there is a calculation
result on the display.
k Angle Units
• Be sure to specify Comp for Mode in the Setup screen.
Example Operation
To convert 4.25 rad to degrees:

k Trigonometric and Inverse Trigonometric Functions
• Be sure to set the angle unit before performing trigonometric function and inverse
trigonometric function calculations.
