Arduino Bitwise Operators - Arduino

What is Arduino Bitwise Operators?

Assume variable A holds 10 and variable B holds 20 then −

Operator name

Operator simple

Description

Example

and

&

Binary AND Operator copies a bit to the result if it exists in both operands.

(A & B) will give 12 which is 0000 1100

or

|

Binary OR Operator copies a bit if it exists in either operand

(A | B) will give 61 which is 0011 1101

xor

^

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

not

~

Binary Ones Complement Operator is unary and has the effect of 'flipping' bits.

(~A ) will give -60 which is 1100 0011

shift left

<<

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

shift right

>>

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
