Only float know how to do this. Python makes this easy for us to handle; as long as we add the decimal ourselves, Python will assume the numbers as floats and perform the operation accordingly. Floats are also called 'floating point' and ints are called 'integers'. It's enough to get a floating point product if just one value in an equation is a float. Let's try a few examples to highlight this."
