I'm trying to find a list of Unity's primitive data types. As I'm searching I'm running into a conceptual collision between modeling primitives and code primitives, two very different subjects.
Examples would be: int, float, double, boolean, void.
When coding I prefer to statically type numbers as int, float or double opposed to leaving it to a catch all Number class.
You don't exactly specify how primitive you want to get.
It's not really "Unity's" primitive data types exactly. Unity uses a customized subset of mono. Most of the primitive types like int, float, enum, etc. are short names for classes in the System library. Duck's links cover the most primitive of these.There are also the classes that were added by Unity (run-time and editor).
