Note: • You will not be able to execute prime factorization while a decimal
value, fraction, or negative value calculation result is displayed. Trying to
do so will cause a math error (Math ERROR). • You will not be able to
execute prime factorization while the result of a calculation that uses Pol,
Rec, ÷R is displayed.
Remainder Calculations
You can use the ÷R function in order to obtain the quotient and remainder
in a division calculation.
To calculate the quotient and remainder of 5 ÷ 2
B
5
!D(÷R) 2 =
Quotient Remainder
b
5
!D(÷R) 2 =
Quotient Remainder
Note: • Only the quotient value of a ÷R calculation is stored in Ans memory.
• Assigning the result of a remainder division calculation to a variable will
assign the quotient value only. Performing the operation 5
!D(÷R)
2
!t(STO))(X) (which assigns the result of 5÷R2 to X) will assign
a value of 2 to X. • If a ÷R calculation is part of a multi-step calculation, only
the quotient is passed on to the next operation. (Example: 10
+ 17 !D
(÷R) 6
= → 10 + 2) • Operation of the f and e keys is disabled while a
remainder division result is on the display.
Cases when Remainder Division becomes
Non-remainder Division
If either of the following conditions exists when you perform a remainder
division operation, the calculation will be treated as normal (non-remainder)
division.
• When either the dividend or the divisor is a very large value
Example: 20000000000
!D(÷R) 17 =
→ Calculated as: 20000000000 ÷ 17
• When the quotient is not a positive integer, or if the remainder is not a
positive integer or positive fractional value
Example:
- 5 !D(÷R) 2 = → Calculated as: –5 ÷ 2
Function Calculations
For actual operations using each function, see the “Examples” section
following the list below.
ππ : π is displayed as 3.141592654, but π = 3.14159265358980 is used for
internal calculations.
e : e is displayed as 2.718281828, but e = 2.71828182845904 is used for
internal calculations.
