# What type are the numbers in a range (1...13)

when you have a statement like

let cards = 1...13

you are including the range 1 to <14. Does this mean that 13.999999 is included? Are the numbers in the range double or float or are they int?

When you are creating a range it is of type int. I tried playing around with it in a playground and I don't think it is possible to create a range of type float or double. So when creating a range of 1 to 5, you are only getting the whole numbers. If you want to try this out in a playground you can use a for-loop.

```let cards = 0...33
for items in cards {
print("\(items) \n")
}
```

Hope this helped,

Thanks Ozzie. I just saw the

``` "0..<14"
```

in the standard editor output area and thought that it might include everything up to 14 but I suppose it's just an easy way to write "whole numbers up to 14."

I tried running your code and it spits out whole numbers. I tried putting Doubles in to the interval and it doesn't like it.

Is there a certain reason why you would like to use a float instead of an int?

Nope, just wanted to see if it was possible because I saw the less than sign. Initially I was trying to see if a double like 5.9 was in the recognized range...not necessarily to make the range go from 3.9...7.9.

I tried this

```let tests = [1, 2.3, 3, 5]

for var i = 0; i < tests.count; i++ {
switch tests {
case 1...3:
println("We can include doubles")
default:
println(tests)
}
}
```

And based on the error it returns I don't think it is possible for a range to even contain a Double.
