F Sharp Bitwise Operators - F Sharp (programming language)

What is F# - Bitwise Operators?

Bitwise operators work on bits and perform bit-by-bit operation. The truth tables for &&& (bitwise AND), ||| (bitwise OR), and ^^^ (bitwise exclusive OR) are as follows −

p &&& q

p ||| q

p ^^^ q

Assume if A = 60; and B = 13; now in binary format they will be as follows −

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

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

(~~~A) will give -61, which is 1100 0011 in 2's complement form.

<<<

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

When you compile and execute the program, it yields the following output −
