What does the operator // denote?

• A. Division
• B. DIV - integer division
• C. Equal to
• D. MOD - remainder after division

Answer: (B)

Integer division returns the whole-number quotient when dividing two numbers. The // operator performs that: it divides and drops any remainder, giving an integer result. For example, 7 // 3 = 2 because 3 goes into 7 twice with a remainder of 1. This is different from ordinary division (which would give 2.333…) and from the remainder operation (which would give 1). Note that with negative numbers, floor division rounds down, so -7 // 3 equals -3, not -2.
