* Flux 0.173.0+

InfluxDB support

`bitwise.urshift()` shifts the bits in `a` right by `b` bits.
Both `a` and `b` are unsigned integers.

##### Function type signature

```js
(a: uint, b: uint) => uint
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### a

(Required)
Left hand operand.

### b

(Required)
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

```
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))}))
```
