Go - Bitwise Operators


Advertisements

The Bitwise operators supported by Go language are listed in the following table. Assume variable A holds 60 and variable B holds 13, then −

Operator Description Example
& Binary AND Operator copies a bit to the result if it exists in both operands. (A & B) will give 12, which is 0000 1100
| Binary OR Operator copies a bit if it exists in either operand. (A | B) will give 61, which is 0011 1101
^ Binary XOR Operator copies the bit if it is set in one operand but not both. (A ^ B) will give 49, which is 0011 0001
<< Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. A << 2 will give 240 which is 1111 0000
>> Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. A >> 2 will give 15 which is 0000 1111

Example

Try the following example to understand all the bitwise operators available in Go programming language −

package main

import "fmt"

func main() {
   var a uint = 60	/* 60 = 0011 1100 */  
   var b uint = 13	/* 13 = 0000 1101 */
   var c uint = 0          

   c = a & b       /* 12 = 0000 1100 */ 
   fmt.Printf("Line 1 - Value of c is %d\n", c )

   c = a | b       /* 61 = 0011 1101 */
   fmt.Printf("Line 2 - Value of c is %d\n", c )

   c = a ^ b       /* 49 = 0011 0001 */
   fmt.Printf("Line 3 - Value of c is %d\n", c )

   c = a << 2     /* 240 = 1111 0000 */
   fmt.Printf("Line 4 - Value of c is %d\n", c )

   c = a >> 2     /* 15 = 0000 1111 */
   fmt.Printf("Line 5 - Value of c is %d\n", c )
}

When you compile and execute the above program it produces the following result −

Line 1 - Value of c is 12
Line 2 - Value of c is 61
Line 3 - Value of c is 49
Line 4 - Value of c is 240
Line 5 - Value of c is 15
