### Shift bits right in an integer

```js
import "bitwise"

bitwise.srshift(a: 1234, b: 2)// Returns 308


```


### Shift bits right in integers in a stream of tables

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

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

```
