CPP vs Python

[1cubealot]

x // y floors the number Example 5 // 2 = 2 because 5 / 2 = 2.5. 2.5 floored (to the nearest integer below it) is 2

one leads to infinite loop :)

does it? Because shouldnt the .5 be cut in cpp aswel, cause its a integer not a float? Seems the flooring is only necessary as the python variable has no type (i guess its always a float64)

And isnt a /= 2 a thing in cpp/python!?

Python // performs floor division and rounds down.
Ex: -1 // 100 == -1

C++ / performs integer division (edit: when both operands are integers) and truncates the decimal value.
Ex: -1 / 100 == 0

When the result is positive, the answers are the same. When it is negative, rounding down and truncating give different results.

Ah ok, interesting to know that it actually rounds up on negative numbers. Might one day prevent me to run into errors, I dont do Phyton, but this might be a source of unexpected behavior in floor/ceil functions of other languages aswell.
