I was trying to work my way around the maximum size of an array (2147483647) when I came across this anomaly :

```auto
void setup() {
  long i = 999_999_967L;
  println(int(i));
}

```

results in : 1000000000  
The value of the long is incorrectly converted without throwing an error.

It turns out that this starts happening at 16777217.  
Is this a bug or just a restriction that is not documented.  
Cheers,  
Adriaan.

From the referents page:  
int() : Converts any value of a primitive data type ( **boolean** , **byte** , **char** , **color** , **float** , **int** , or **long** ) or String to its integer representation.

This does work but for a long this stops at 16777217.

At a a different place it says :  
you’ll usually have to convert to a **int** using the **(int)** syntax.

This works for all values.  
Thanks for your help.

Adriaan.
