bit manipulation - Python How to get set bit - Stack Overflow

To get the bit number of the highest bit set, you could use. int.bit_length()-1 This is much more efficient then using math.log() or the other function you had posted. EDIT: As requested, timeit results are posted: python -m timeit -s 'import math;x=100' 'int(math.log(x,2))' 1000000 loops, best of 3: 0.5 usec per loop

BitManipulation - Python Wiki

bitLen() counts the actual bit length of a Python integer, that is, the number of the highest non-zero bit plus 1. Zero, with no non-zero bit, returns 0. Zero, with no non-zero bit, returns 0. As should be expected from the quote above about "the illusion of an infinite string of sign bits extending to the left," a negative number throws the computer into an infinite loop.

Solved: get bits from byte in Python - SourceTrail

3. Use bitwise AND: Finally, we apply the bitwise AND operator (&) between the shifted byte and the mask.This operation will extract only the desired bits, leaving the rest unchanged. Python’s Bitwise Operators and Libraries. Python’s bitwise operators play a significant role in extracting bits from bytes. These operators perform operations at the bit level, allowing us to manipulate individual bits within a byte.

Position of rightmost set bit - GeeksforGeeks

Given an integer n, the task is to return the position of the first set bit from right to left in the binary representation n. If n is equal to 0 (no set bits present), then return 0. Note: Position of rightmost bit is 1. Examples: Input: n = 18 Output: 2 Explanation: Binary Representation of 18 is 10010, hence position of first set bit from right is 2. Input: n = 19 Output: 1 Explanation: Binary Representation of 19 is 10011, hence position of first set bit from right is 1. Using 2's ...

Python Program to Get nth Bit of a Number - BTech Geeks

Given a number and the bit position, the task is to get the bit that is present at that position (in the binary representation of a number). Bitwise & Operator: If both bits are 1, sets each bit to 1. Examples: Example1: Input: Given Number = 2 Bit position(in range 0-31)= 0. Output: The bit present at the given position{ 0 } for a given number ...

how to get the thighest bit position in big integers? - Post.Byes

Hi, I'm using python to develop some proof-of-concept code for a cryptographic application. My code makes extended use of python's native bignum capabilities. In many cryptographic applications there is the need for a function 'get_highest_bit_num' that returns the position number of the highest set bit of a given integer.

sys.maxint in Python - GeeksforGeeks

In Python 2, sys.maxint refers to the maximum value an integer can hold on a given platform. This value is: 2³¹ - 1 = 2147483647 on a 32-bit system; 2⁶³ - 1 = 9223372036854775807 on a 64-bit system; sys.maxint was typically used as a very large number in algorithms requiring an upper bound, like finding minimum values in a list.. Note: sys.maxint has been removed in Python 3.Use sys.maxsize as a practical alternative. Examples of sys.maxint Example 1: Using sys.maxint to Find the ...
