public interface CollectionNumber
```
A collection of numeric (primitive) elements. It provides basis iteration and copy to array.
The method names are taken from Collection, though not all methods are specified. At this moment, the class is read-only. If in the future the class is extended, the new methods should match the names from Collection.

- Method Detail
  - iterator
```
IteratorNumber iterator()
```
    Returns an iterator over the elements of the collection.
    
    Returns:
    
    a new iterator
  - size
```
int size()
```
    Returns the number of elements in the collection.
    
    Returns:
    
    the number of elements in the collection
  - toArray
```
default <T> T toArray(T array)
```
    Type Parameters:
    
    T - the type of the array
    
    Parameters:
    
    array - the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.
    
    Returns:
    
    an array containing the elements
    
    Throws:
    
    ArrayStoreException - if the type of the specified array is not a primitive number array
    
    NullPointerException - if the specified array is null
