Linear Display (LineIO) causes fractions and  
other expressions to be displayed in a single 
line. 

Note:  • The calculator switches to Linear Display automatically whenever 
you enter the STAT, BASE-N, MATRIX, or VECTOR Mode.  • In this manual, 
the 

 symbol next to a sample operation indicates Natural Display, while 

the 

1 symbol indicates Linear Display.

Deg  Rad  Gra     Specifies degrees, radians or grads as the angle 
unit for value input and calculation result display.

Note: In this manual, the 

B symbol next to a sample operation indicates 

degrees, while the 

* symbol indicates radians. 

Fix  Sci  Norm     Specifies the number of digits for display of a 
calculation result.
Fix: The value you specify (from 0 to 9) controls the number of decimal  
places for displayed calculation results. Calculation results are rounded off 
to the specified digit before being displayed.

Example: 

1 100 ÷ 7 = 14.286  (Fix 3)

   

                     14.29      (Fix 2)

Sci: The value you specify (from 1 to 10) controls the number of significant 
digits for displayed calculation results. Calculation results are rounded off to 
the specified digit before being displayed.

Example: 

1 1 ÷ 7 = 1.4286 s 10

–1

  (Sci 5)

                                      1.429 

s 10

    (Sci 4)

Norm: Selecting one of the two available settings (Norm 1, Norm 2) 
determines the range in which results will be displayed in non-exponential 
format. Outside the specified range, results are displayed using exponential 
format.

Aab/c  A d/c     Specifies either mixed fraction (ab/c) or improper 
fraction (d/c) for display of fractions in calculation results. 

ACMPLX  a+b

 ; 

rθ   Specifies either rectangular coordinates 

(

+

) or polar coordinates (

θ) for EQN Mode solutions. 

ASTAT  ON ; OFF     Specifies whether or not to display a FREQ 
(frequency) column in the STAT Mode Stat Editor. 

ADisp   Dot ; Comma    Specifies whether to display a dot or 
a comma for the calculation result decimal point. A dot is always displayed 
during input. 

Note: When dot is selected as the decimal point, the separator for multiple  
results is a comma (,). When comma is selected, the separator is a 
semicolon (;).

A;CONT        Adjusts display contrast. See “Adjusting Display 
Contrast” for details.
