What would be the result of executing the following code?
|
 0 0.0 0.5 1 |
Explanation
In Python, operator / is for float division (or true division) and operator // is for integer division (or floor division)
// does performs division and the result will be floored (rounded DOWN to the next lower integer) and the result will be integer if both operands are integers and will be float with .0 if either operand is a float.
Python coercion (type casting) rules promotes conversion of lower data type (integer) to higher data type (float) to avoid data loss. Flooring always moves to the lower integer value. So, floor of x is the largest integer less than or equal to x.
3 // 2 = 1
3.0 // 2 = 1.0
3 // 2.0 = 1.0
3.0 // 2.0 = 1.0
-100 // 33 = -4
-100 // 33.1 = -4.0
-100 // -33 = 3
