I am not seeing commas or decimal points in my intergers or doubles like in the video, do I need to change a preference?

I don't really get your question , however to show decimal its either you use double or float like :

          var number :Double = 2.3333
          var numbers :Float = 56.333545

Remember Int is for integers and if you are passing decimal value to it, it will convert it to integer .For example

                       var numbers :Int = 1.36

It will display 1 that is it ... Hope that helps.

Thanks for the quick reply, sorry if it wasn't a clear question. In the video example, the instructor's output had a comma in 2,014 without having to use " var numbers :Int = 1.36", and had a decimal point in the the second example without having to use Double or Float. However, when I wrote the same syntax, there was no comma or decimal point.

I am not sure if this even matters, but if it does, I am wondering whether or not the code I wrote was wrong, or if there is something I have to change in xcode.

So when I write: let year = 2014 ; it shows up as 2014, NOT 2,014 like in the video or var version = 1.0 ; it shows up as 1, NOT 1.0 like in the video.

Is this clearer? It's possible this doesn't even mean anything, but I am wondering if I'm doing something wrong that I can't get my output to look like the instructor's.
