Bitwise Operators in Go Programming Language
Bitwise operators are used to compare (binary) numbers.
| Operator | Name | Description |
|---|---|---|
| & | AND | Sets each bit to 1 if both bits are 1 |
| | | OR | Sets each bit to 1 if one of two bits is 1 |
| ^ | XOR | Sets each bit to 1 if only one of two bits is 1 |
| << | Zero fill left shift | Shift left by pushing zeros in from the right and let the leftmost bits fall off |
| >> | Signed right shift | Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off |
The following example will show you these bitwise operators in action:
Example
package main
import "fmt"
func main() {
var x uint = 9 //0000 1001
var y uint = 65 //0100 0001
var z uint
z = x & y
fmt.Println("x & y =", z)
z = x | y
fmt.Println("x | y =", z)
z = x ^ y
fmt.Println("x ^ y =", z)
z = x << 1
fmt.Println("x << 1 =", z)
z = x >> 1
fmt.Println("x >> 1 =", z)
}
Output
x & y = 1
x | y = 73
x ^ y = 72
x << 1 = 18
x >> 1 = 4
