u  Angle Units, Coordinate Conversion, Sexagesimal Operations (ANGLE) 
[OPTN]-[ANGLE]
• {°}/{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

• {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.
