u Calculation Result Display Range with 
π 
  A calculation results is displayed using π  format in the following cases.
  • When the calculation result can be displayed in the form 
n π 
n  is an integer up to |10 
6 
|.
  • When the calculation result can be displayed in the form 
a
b
c
 π  or 
b
c
 π 
    However, {number of 
a  digits + number of b  digits + number of c  digits} must be 9 or less 
when the above 
a

c
  or

c
  is reduced.*

 Also, the maximum number of allowable c  digits is 
three.*

 When  c  < b , the number of a , b , and c  digits are counted when the fraction is converted 
from an improper fraction ( 
b
c
 ) to a mixed fraction ( 
a
b
c
 ).

 When “Manual” is specified for the Setup screen “Simplify” setting, the calculation result 
may be displayed in decimal format, even if these conditions are met.

k Multiplication Operations without a Multiplication Sign
You can omit the multiplication sign (×) in any of the following operations.
• Before Type A functions (1 on page 2-2) and Type C functions (6 on page 2-2), except for 
negative signs
Example 1 
2sin30, 10log1.2, 2
'
3
, 2Pol(5, 12), etc.
• 
Before constants, variable names, memory names
Example 2  2π, 2AB, 3Ans, 3Y
1, etc.
• Before an open parenthesis
Example 3  3(5 + 6), (A + 1)(B – 1), etc.
If you execute a calculation that includes both division and multiplication operations in which 
a multiplication sign has been omitted, parentheses will be inserted automatically as shown in 
the examples below.
• When a multiplication sign is omitted immediately before an open parenthesis or after a 
closed parenthesis.*
