How do you write out a double for the amount : "500.0" ?

Consider the code below.

struct Expense {
    var description: String  // Stored property
    var amount: Double  // Stored property
}

var travel = Expense(description: "Flight to Cupertino", amount:500.00)

The great thing about struct types is that you can reference the stored properties easily, and change them too.

Consider the following examples.

print(travel.description)  // This would print out "Flight to Cupertino"
travel.amount = 550.00  // This would change the amount property to 550.00

This makes it really easy to have a single value (travel in this case) hold multiple stored values. :)
