Using numbers in functions

[Lyranile]

It's a very simple question, I want to call my function 14, like this:

fn 14() {
    println!("some function");
}

Is it possible?

Also, why is sinus being called like this:
3.14f32.sin()
When f is actually not part of the number, it is actually indicating the type?

3.14f32.sin()
When f is actually not part of the number, it is actually indicating the type?

Yes, indeed. The f32 part is called the suffix of the number literal 3.14. I would strongly recommend you to read The Book first if you haven't already. In this case, https://doc.rust-lang.org/stable/book/ch03-02-data-types.html#integer-types should clear things up.

I want to call my function 14 […] Is it possible?

No it's not. "Anything starting with" a digit (0-9) denotes a number literal which represents a number constant in some base and of some type. Therefore, names (so called identifiers) of variables and items like functions must not start with a digit, otherwise it would be grammatically ambiguous.
