NettetThis operator performs a Bitwise right shift on the operands and stores the result in the left operand. Input: a = 15 b = 2 a >>= b print (a) Output: 3 The binary value of 15 is 1111, so when the Bitwise right shift operation is performed on ‘a’, we get 0011, which is 3 in decimal.

Nettet5. apr. 2024 · The << operator is overloaded for two types of operands: number and BigInt.For numbers, the operator returns a 32-bit integer. For BigInts, the operator returns a BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt left shift if both operands becomes BigInts; otherwise, it converts both … NettetThe left and right shift operators move the bits a number of positions to the left or right, respectably. New bits shifted in are of 0 value. 00:21 Because each bit in a binary number is a power of 2, a bit shift is equivalent to a multiplication or division by 2.

"NettetThe Bitwise right shift operator (>>) takes the two numbers and right shift the bits of first operand by number of place specified by second operand. For example: for right shifting the bits of x by y places, the expression ( x>>y) can be used. It is equivalent to dividing x by 2y. The example below describes how right shift operator works: " - Left and right shift operators in python
