Bitwise operators

Left shift

The left-shift operator causes the bits in the left value (either a variable or a literal)to be shifted to the left by the number of positions specified by the bits in the right value.

Example

with console from std:io

var a = 20 << 2

console.out(a) //Output: 80

Right shift

The right-shift operator causes the bits in the left value (either a variable or a literal)to be shifted to the right by the number of positions specified by the bits in the right value.

Example

with console from std:io

var a = 8 >> 2

console.out(a) //Output: 2

Bitwise and

The result of the bitwise and (denoted by

`&`

) is 1 if the corresponding bits of two operands are 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0.Example

with console from std:io

â€‹

var a = 12 //00001100 in binary

var b = 25 //00011001 in binary

â€‹

console.out(a&b) //Output: 8

Bitwise or

The result of the bitwise or (denoted by

`|`

) is 1 if at least one corresponding bit of two operands is 1.Example

with console from std:io

â€‹

var a = 12

var b = 25

â€‹

console.out(a|b) //Output: 29

Bitwise xor

The result of the bitwise xor (denoted by

`^`

) is 1 if the corresponding bits of two operands are opposite.Example

with console from std:io

â€‹

var a = 12

var b = 25

â€‹

console.out(a^b) //Output: 21

One's complement

The bitwise complement (denoted by

`~`

) changes 1 to 0 and 0 to 1.Example

with console from std:io

â€‹

var a = 35 //00100011 in binary

â€‹

console.out(~a) //Output: 220

â€‹
