# ee.Array.bitwiseAnd

On an element-wise basis, calculates the bitwise AND of the input values.

<br />

| Usage | Returns |
|---|---|
| `Array.bitwiseAnd(right)` | Array |

| Argument | Type | Details |
|---|---|---|
| this: `left` | Array | The left-hand value. |
| `right` | Array | The right-hand value. |

## Examples

### Code Editor (JavaScript)

```javascript
var empty = ee.Array([], ee.PixelType.int8());
print(empty.bitwiseAnd(empty));  // []

print(ee.Array(0).bitwiseAnd(ee.Array(0)));  // 0
print(ee.Array(0).bitwiseAnd(ee.Array(1)));  // 0
print(ee.Array(1).bitwiseAnd(ee.Array(0)));  // 0
print(ee.Array(1).bitwiseAnd(ee.Array(1)));  // 1
print(ee.Array(0xFF).bitwiseAnd(ee.Array(0xFFFF)));  // 255
print(ee.Array(0xFFFF).bitwiseAnd(ee.Array(0xFF)));  // 255

print(ee.Array(-1).bitwiseAnd(ee.Array(0xFF)));  // 255
print(ee.Array(-1).bitwiseAnd(ee.Array(-2)));  // -2

print(ee.Array([6, 6]).bitwiseAnd(ee.Array([1, 11])));  // [0,2]
```
Python setup

See the [Python Environment](https://developers.google.com/earth-engine/guides/python_install) page for information on the Python API and using
`geemap` for interactive development.

```python
import ee
import geemap.core as geemap
```

### Colab (Python)

```python
empty = ee.Array([], ee.PixelType.int8())
display(empty.bitwiseAnd(empty))  # []

display(ee.Array(0).bitwiseAnd(ee.Array(0)))  # 0
display(ee.Array(0).bitwiseAnd(ee.Array(1)))  # 0
display(ee.Array(1).bitwiseAnd(ee.Array(0)))  # 0
display(ee.Array(1).bitwiseAnd(ee.Array(1)))  # 1
display(ee.Array(0xFF).bitwiseAnd(ee.Array(0xFFFF)))  # 255
display(ee.Array(0xFFFF).bitwiseAnd(ee.Array(0xFF)))  # 255

display(ee.Array(-1).bitwiseAnd(ee.Array(0xFF)))  # 255
display(ee.Array(-1).bitwiseAnd(ee.Array(-2)))  # -2

display(ee.Array([6, 6]).bitwiseAnd(ee.Array([1, 11])))  # [0, 2]
```
