- [Perform a bitwise AND NOT operation on a stream of tables](#perform-a-bitwise-and-not-operation-on-a-stream-of-tables)

### Perform a bitwise AND NOT operation

```js
import "bitwise"

bitwise.sclear(a: 1234, b: 4567)// Returns 1024


```


### Perform a bitwise AND NOT operation on a stream of tables

```js
import "bitwise"
import "sampledata"

sampledata.int()
    |> map(fn: (r) => ({r with _value: bitwise.sclear(a: r._value, b: 3)}))

```
