• Truncation for negative integers

  • Python

    # Floor division (rounds towards negative infinity)
    print(f"5 // 2: {5 // 2}")     #  2
    print(f"-5 // 2: {-5 // 2}")   # -3
    
    # Truncation towards zero (using math.trunc)
    print(f"math.trunc(5 / 2): {math.trunc(5 / 2)}")    #  2
    print(f"math.trunc(-5 / 2): {math.trunc(-5 / 2)}")  # -2
