Remainder Calculations

You can use the ÷R function to obtain the quotient and remainder in a
division calculation.
Example: To calculate the quotient and remainder of 5 ÷ 2 (quotient = 2,
remainder = 1)
(MthIO-MathO)
(LineIO)
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
(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
• Operation of the

Cases when Remainder Division becomes Non-remainder Division
If either of the conditions below 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
→ 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
→ Calculated as: -5 ÷ 2
