# Perl Bitwise Operators Example

There are following Bitwise operators supported by Perl language, assume if \$a = 60; and \$b = 13 −

OperatorDescriptionExample
& 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 eather 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 Ones Complement Operator is unary and has the efect of 'flipping' bits. (~\$a ) will give -61 which is 1100 0011 in 2's complement form due to a signed binary number.
<< 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 Perl. Copy and paste the following Perl program in test.pl file and execute this program.

```#!/usr/local/bin/perl

use integer;

\$a = 60;
\$b = 13;

print "Value of \\$a = \$a and value of \\$b = \$b\n";

\$c = \$a & \$b;
print "Value of \\$a & \\$b = \$c\n";

\$c = \$a | \$b;
print "Value of \\$a | \\$b = \$c\n";

\$c = \$a ^ \$b;
print "Value of \\$a ^ \\$b = \$c\n";

\$c = ~\$a;
print "Value of ~\\$a = \$c\n";

\$c = \$a << 2;
print "Value of \\$a << 2 = \$c\n";

\$c = \$a >> 2;
print "Value of \\$a >> 2 = \$c\n";
```

When the above code is executed, it produces the following result −

```Value of \$a = 60 and value of \$b = 13
Value of \$a & \$b = 12
Value of \$a | \$b = 61
Value of \$a ^ \$b = 49
Value of ~\$a = 18446744073709551555
Value of \$a << 2 = 240
Value of \$a >> 2 = 15
```
