Int division in scala

I have two Int values in Scala.

scala> val a = 3
a: Int = 3

scala> val b = 5
b: Int = 5

Now, I want to divide them and get Float. With as little boilerplate as possible.

If I do a/b, I get

scala> a/b
res0: Int = 0

I cannot do simple Java (float).

scala> ((Float)a)/b
<console>:9: error: value a is not a member of object Float
              ((Float)a)/b
                      ^

What should I do?
