```
public class JsArrayNumber
extends JavaScriptObject
```
A simple wrapper around a homogeneous native array of numeric values. All native JavaScript numeric values are implicitly double-precision, so only double values may be set and retrieved. This class may not be directly instantiated, and can only be returned from a native method. For example, native JsArrayNumber getNativeArray() /*-{ return [1.1, 2.2, 3.3]; }-* /;

```
- Method Detail
  - get
```
public final double get(int index)
```
    Gets the value at a given index. If an undefined or non-numeric value exists at the given index, a type-conversion error will occur in Development Mode and unpredictable behavior may occur in Production Mode.
    
    Parameters:
    index - the index to be retrieved
    
    Returns:
    the value at the given index
  - join
```
public final java.lang.String join()
```
    Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.
  - join
```
public final java.lang.String join(java.lang.String separator)
```
    Convert each element of the array to a String and join them with a comma separator. The value returned from this method may vary between browsers based on how JavaScript values are converted into strings.
  - length
```
public final int length()
```
    Gets the length of the array.
    
    Returns:
    the array length
  - push
```
public final void push(double value)
```
    Pushes the given number onto the end of the array.
  - set
```
public final void set(int index,
       double value)
```
    Sets the value value at a given index. If the index is out of bounds, the value will still be set. The array's length will be updated to encompass the bounds implied by the added value.
    
    Parameters:
    index - the index to be set
    value - the value to be stored
  - setLength
```
public final void setLength(int newLength)
```
    Reset the length of the array.
    
    Parameters:
    newLength - the new length of the array
  - shift
```
public final double shift()
```
    Shifts the first value off the array.
    
    Returns:
    the shifted value
  - unshift
```
public final void unshift(double value)
```
    Shifts a value onto the beginning of the array.
    
    Parameters:
    value - the value to the stored
