3. Specifying the Angle Unit and Display Format
Before performing a calculation, you should use the Setup screen to specify the angle unit and
display format.
k Setting the Angle Unit [SET UP] - [Angle]
1. On the Setup screen, highlight “Angle”.
2. Press the function key for the angle unit you want to specify, then press J.
• { Deg } / { Rad } / { Gra } ... {degrees}/{radians}/{grads}
• The relationship between degrees, grads, and radians is shown below.
360° = 2 π radians = 400 grads
90° = π /2 radians = 100 grads
k Setting the Display Format [SET UP] - [Display]
1. On the Setup screen, highlight “Display”.
2. Press the function key for the item you want to set, then press J.
• { Fix } / { Sci } / { Norm } / { Eng } ... {fixed number of decimal places specification}/
{number of significant digits specification}/{normal display}/{Engineering mode}
u To specify the number of decimal places ( Fix)
Example To specify two decimal places
1(Fix) cw
Press the number key that corresponds to the number of decimal places you want to specify
(
n = 0 to 9).
• Displayed values are rounded off to the number of decimal places you specify.
