Set and Clear Bits in Golang

There are bitwise operators in golang for bit manipulation. However, there is an unusual NOT operator. golang uses the ^ operator for NOT.

Code

NOT of a number

a := 101
notOfA := a ^ a // 101 ^ 101 = 010 

Setting a bit of a number

a := 101
b := 1 << 2 // second second bit
setBit := a | b // 101 | 010 = 111 

Clear a bit

a := 101
b := 1 << 2 // second second bit

// 101 & ^(010) => 101 & 101 => 101
setBit := a &^ b
