What does the question mark in "Decimal?" mean?

Question

I am following tutorials about MVC4 asp.net. The tutorials are using Decimal like this:

     public Decimal x{ set; get; }
     public Decimal? y{ set; get; }

what does it mean when using ? after Decimal

It's actually a `Nullable` – Jordy Langen Dec 19 '13 at 08:07 — Jordy Langen, Dec 19 '13 at 08:07
