Example 1

easy
What is the result of integer division 17÷517 \div 5 and 17mod  517 \mod 5? Explain the difference from regular division.

Solution

  1. 1
    Step 1: Regular division: 17÷5=3.417 \div 5 = 3.4.
  2. 2
    Step 2: Integer division (floor): 17 DIV 5=317 \text{ DIV } 5 = 3 (discard the decimal part).
  3. 3
    Step 3: Modulo: 17 MOD 5=217 \text{ MOD } 5 = 2 (the remainder after dividing 17 by 5).

Answer

DIV: 3, MOD: 2. Regular division gives 3.4.
Integer division returns the whole-number quotient, while modulo returns the remainder. Together they fully describe the result: 17=5×3+217 = 5 \times 3 + 2.
