    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    Hmmm. I just answered a similar question. But here you go anyway.

    cout << (float)answer;

    but you may also want to do your operations like this:
    Code:
    float answer;
    answer = 10 - 2.0/5.0 - 8.0/5.0 - 3.0/8.0;

    master, the reason you just answered a similar questioned is because i was going to answer this post, and found that i had no idea either!

    but anyway, you shouldn't have to put:

    Code:
    cout << (float)answer << endl;
    the (float) type casting is not necessary, but if you still cant do it that way just use double instead

    I see that the cycle of life has been completed then Anyway, I'm not too sure way the 2f/5f thing didn't work for you. I'm using mingw though. I don't know why something like that would make a difference. Oh well.
