The basic assignment operator is equal ( = ), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x . The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples.
Simple assignment operator is used to assign a value to a variable. The assignment operation evaluates to the assigned value. Chaining the assignment operator is possible in order to assign a single value to multiple variables. See the example.
Addition assignment
The addition assignment operator adds the value of the right operand to a variable and assigns the result to the variable. The types of the two operands determine the behavior of the addition assignment operator. Addition or concatenation is possible. See the addition operator for more details.
Subtraction assignment
The subtraction assignment operator subtracts the value of the right operand from a variable and assigns the result to the variable. See the subtraction operator for more details.
Multiplication assignment
The multiplication assignment operator multiplies a variable by the value of the right operand and assigns the result to the variable. See the multiplication operator for more details.
Division assignment
The division assignment operator divides a variable by the value of the right operand and assigns the result to the variable. See the division operator for more details.
Remainder assignment
The remainder assignment operator divides a variable by the value of the right operand and assigns the remainder to the variable. See the remainder operator for more details.
Exponentiation assignment
The exponentiation assignment operator evaluates to the result of raising first operand to the power second operand. See the exponentiation operator for more details.
Left shift assignment
The left shift assignment operator moves the specified amount of bits to the left and assigns the result to the variable. See the left shift operator for more details.
Right shift assignment
The right shift assignment operator moves the specified amount of bits to the right and assigns the result to the variable. See the right shift operator for more details.
Unsigned right shift assignment
The unsigned right shift assignment operator moves the specified amount of bits to the right and assigns the result to the variable. See the unsigned right shift operator for more details.
Bitwise AND assignment
The bitwise AND assignment operator uses the binary representation of both operands, does a bitwise AND operation on them and assigns the result to the variable. See the bitwise AND operator for more details.
Bitwise XOR assignment
The bitwise XOR assignment operator uses the binary representation of both operands, does a bitwise XOR operation on them and assigns the result to the variable. See the bitwise XOR operator for more details.
Bitwise OR assignment
The bitwise OR assignment operator uses the binary representation of both operands, does a bitwise OR operation on them and assigns the result to the variable. See the bitwise OR operator for more details.
Left operand with another assignment operator
In unusual situations, the assignment operator (e.g. x += y ) is not identical to the meaning expression (here x = x + y ). When the left operand of an assignment operator itself contains an assignment operator, the left operand is evaluated only once. For example:

The <<= operator shifts the bits of result left by the number of bits specified in expression . For example:
The variable temp has a value of 56 because 14 (00001110 in binary) shifted left two bits equals 56 (00111000 in binary). Bits are filled in with zeroes when shifting.
For information on when a run-time error is generated by the <<= operator, see the Operator Behavior table.

Python - left shift operator assignment
The Bitwise left shift assignment operator (<<=) assigns the first operand a value equal to the result of Bitwise left shift operation of two operands.
(x <<= y) is equivalent to (x = x << y)
The Bitwise left shift operator (<<) takes the two numbers and left shift the bits of first operand by number of place specified by second operand. For example: for left shifting the bits of x by y places, the expression ( x<<y ) can be used. It is equivalent to multiplying x by 2 y .
The example below describes how left shift operator works:
The code of using left shift operator (<<) is given below:
The output of the above code will be:
Example: Count number of 1 Bits in a positive integer
Consider an integer 1000. In the bit-wise format, it can be written as 1111101000. However, all bits are not written here. A complete representation will be 32 bit representation as given below:
Bitwise AND operation with 1 at any bit results into 1 if the bit is 1 or 0 if the bit is 0. Performing such operation at every bit, and counting the number of 1 gives the count of 1 bits in the given positive integer. To achieve this bitwise left shift assignment operator can be used as shown in the example below:
The above code will give the following output:

The Right Shift Assignment Operator is represented by “>>=”. This operator shifts the first operand to the right and assigns the result to the variable. It can also be explained as shifting the first operand to the right in a specified amount of bits which is the second operand integer and then assigning the result to the first operand.
Where –
- a is the first operand, and
- b is the second operand.
Example 1: In this example, we will see the implementation of the right shift assignment.
Example 2: In this example, we will see assigning the right shift operator to the variable.

The left shift assignment (<<=) operator performs left shift on the two operands and assigns the result to the left operand. Try it. Syntax. js. x <<= y Description. x <<= y is equivalent to x = x << y, except that the expression x is only evaluated once. Examples. Using left shift assignment. js.
The Left Shift Assignment Operator is represented by "<<=". This operator moves the specified number of bits to the left and assigns that result to the variable. We can fill the vacated place by 0. The left shift operator treats the integer stored in the variable to the operator's left as a 32-bit binary number. This can also be explained ...
Bitwise Shift Operators. They are classified into two categories left shift and the right shift. Left Shift(<<): The left shift operator, shifts all of the bits in value to the left a specified number of times. Syntax: value << num. Here num specifies the number of position to left-shift the value in value.
The Bitwise left shift assignment operator (<<=) assigns the first operand a value equal to the result of Bitwise left shift operation of two operands. The Bitwise left shift operator (<<) takes the two numbers and left shift the bits of first operand by number of place specified by second operand. For example: for left shifting the bits of x ...
Use the correct assignment operator that will result in x being 15 (same as x = x + y ). Start the Exercise. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.
The left shift assignment operator (<<=) moves the specified amount of bits to the left and assigns the result to the variable. The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, ...
The basic assignment operator is equal ( = ), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x. The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples. Name. Shorthand operator.
The Bitwise left shift assignment operator (<<=) assigns the first operand a value equal to the result of Bitwise left shift operation of two operands. The Bitwise left shift operator (<<) takes the two numbers and left shift the bits of first operand by number of place specified by second operand. For example: for left shifting the bits of x ...
The <<= operator shifts the bits of result left by the number of bits specified in expression. For example: temp = 14. temp <<= 2. document.write (temp); To run the code above, paste it into JavaScript Editor, and click the Execute button. The variable temp has a value of 56 because 14 (00001110 in binary) shifted left two bits equals 56 ...
The bitwise left shift operator can be used to clear a specific bit in an integer to 0. This is done by left shifting 1 by the desired bit position, taking the bitwise complement (~) of the result, and then using the bitwise AND (&) operator to clear the bit. // Clear the nth bit to 0. int bitmask = ~(1 << n);
Left Shift (<<) It is a binary operator that takes two numbers, left shifts the bits of the first operand, and the second operand decides the number of places to shift. In other words, left-shifting an integer " a " with an integer " b " denoted as ' (a<<b)' is equivalent to multiplying a with 2^b (2 raised to power b). Syntax: a << b;
Expressions and operators. Left shift (<<) The left shift operator ( <<) shifts the first operand the specified number of bits to the left. Excess bits shifted off to the left are discarded. Zero bits are shifted in from the right. JavaScript Demo: Expressions - Left shift operator. 9.
We use an assignment operator to store and update data within a program. They enable programmers to store data in variables and manipulate that data. The most common assignment operator is the equals sign (=), which assigns the value on the right side of the operator to the variable on the left side. Types of Assignment Operators: Simple ...
The Bitwise left shift assignment operator (<<=) assigns the first operand a value equal to the result of Bitwise left shift operation of two operands. The Bitwise left shift operator (<<) takes the two numbers and left shift the bits of first operand by number of place specified by second operand. For example: for left shifting the bits of x ...
An assignment operator assigns a value to its left operand based on the value of its right operand.. Overview. The basic assignment operator is equal (=), which assigns the value of its right operand to its left operand.That is, x = y assigns the value of y to x.The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples.
In the following expression, the left shift assignment operation is carried. int x = 7; x <<= 32; printf("x = %d\n",x); ... Precedence while using right and left shift operators. 39. Why does it make a difference if left and right shift are used together in one expression or not? 1.
The syntax of the left-shift operator in Java is given below, Syntax: x << n. Here, x: an integer. n: a non-negative integer. Return type: An integer after shifting x by n positions toward left. Exception: When n is negative the output is undefined. Below is the program to illustrate how we can use the left shift operator in Java.
I've been trying to implement a lightweight unsigned big numbers (big endian) class in c++, and am storing the numbers as base-2^32 numbers in a uint32_t array. But i've have been having some troub...
The Right Shift Assignment Operator is represented by ">>=".This operator shifts the first operand to the right and assigns the result to the variable. It can also be explained as shifting the first operand to the right in a specified amount of bits which is the second operand integer and then assigning the result to the first operand.
