How can I cast (n+n%2) expression to float so it will give me float number after division?

I am trying to get float number result from this c++ code, but i cannot for some reason:

int n = 5;

std::cout << static_cast<float>(n + n % 2) / 2 << std::endl;

Console output is 3. Could you explain what I am missing in this expression?

You can use static_cast, as you did in your example.

Your are missing nothing. The cast to float was achieved successfully and 3 is the correct result of 6.f / 2 using floating point division.
