### a
({{< req >}})
Left hand operand.



### b
({{< req >}})
Number of bits to shift.

- [Shift bits right in unsigned integers in a stream of tables](#shift-bits-right-in-unsigned-integers-in-a-stream-of-tables)

### Shift bits right in an unsigned integer

```js
import "bitwise"

bitwise.urshift(a: uint(v: 1234), b: uint(v: 2))// Returns 308 (uint)


```


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

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

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

```
