So what happens if you combine two numbers of different type? If you try it out, you can see that our result will be of the type that carries more precision. Thus, if we add a float and an int, we obtain a float.

> 3.4//3
1.0 # Floored, but still a float.

Imaginary/Complex Numbers

We may represent imaginary numbers by adding either a j or J to our expression.

> 5+3j
(5+3j)
