arithmetic right shift calculator
The binary representation of 10 is 1010.
When we shift it two positions to the right, we get 0010, which is equivalent to the decimal number 2.
How do you do arithmetic shift right?
Arithmetic Right Shift:
In this shift, each bit is moved to the right one by one and the least significant(LSB) bit is rejected and the empty most significant bit(MSB) is filled with the value of the previous MSB.
How much is 1
1 << 0 = 1 1 << 1 = 2 1 << 2 = 4 1 << 3 = 8 etc This is left shift operator.
All the bits are shifted one place toward left.
Resulting is *2 of the value by shifting value.
How do you calculate right shift?
It is a binary operator that takes two numbers, right shifts the bits of the first operand, and the second operand decides the number of places to shift.
In other words, right-shifting an integer “a” with an integer “b” denoted as '(a>>b)' is equivalent to dividing a with 2^b.
