• {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.
I Angle Units
• Be sure to specify Comp for Mode in the Setup screen.
Example
Operation
To convert 4.25 rad to degrees:
243.5070629
*(E)(ANGL)**(r)U
47.3° + 82.5rad = 4774.20181°
