bitwise.srshift() function	`bitwise.srshift()` shifts the bits in `a` right by `b` bits. Both `a` and `b` are integers.	flux_0_x_ref name parent identifier bitwise.srshift bitwise bitwise/srshift	101

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

Function type signature

(a: int, b: int) => int

{{% caption %}}For more information, see Function type signatures.{{% /caption %}}

Parameters

a

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

b

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

Examples

• Shift bits right in an integer
• Shift bits right in integers in a stream of tables

Shift bits right in an integer

import "bitwise"

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

Shift bits right in integers in a stream of tables

import "bitwise"
import "sampledata"

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