The subject of your message says that you want a random float rather
than a random integer.  If you want a random float between 0 and 5, do
the following:

@num = rand * 5

Otherwise, you're doing fine with the method you're using to get a
random integer.

You passed your integer to a method that expects a string.  That's why
something is ultimately calling the length method on the object you
passed in.  Look up the to_s method for the Integer class and see if
that helps you out.
