problem with floats

i'm having a problem with floats.

Code:

---

int a, b;
float percentage;

// ...

if (a == b)
        setbar(0.5);
else {
        percentage = a/(a+b);
        // check here
        setbar(percentage);
}

---

and set bar is defined like this:

Code:

---

setbar(float percentage);

---

but percentage is never a float. if i check it right after i set it (the comment "check here") or within the function setbar, it's either 0 or 1, like it's just an int. the only time it works is if a==b, in which case i tell it to pass 0.5 as the argument. The one thing i notice is that whenever b != 0, percentage is always 0, leading to the conclusion that a/(a+b) is doing the same thing as (int)(a/(a+b))

what am i doing wrong?

Maybe this would be of some help to you.

thanks, i finally got it to work.
