    There are fundamental limits on how many useful digits a number like that will contain anyway. So you can write 10.73333 for your purposes. If you really care, you can do some math like 10.4 + 1.0 / 3.0

    Yeah, divide by 3, like every other feet to yard conversion. The math will be correct.

    If you use functions from math.h, then yes you do. I don't know from the information that you gave me that you are actually using any math functions. You can divide without a library.

    The link in my previous post actually lists all of them. If you aren't using any, then no reason to include cmath exists.
