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

To get the bit number of the highest bit set, you could use. This is much more efficient then using math.log() or the other function you had posted. EDIT: As requested, timeit results are posted: Also, using math.log will yeild inaccurate results for values higher than 2**29.

BitManipulation - Python Wiki

Here is some information and goals related to Python bit manipulation, binary manipulation. Some tasks include: Turn "11011000111101..." into bytes, (padded left or right, 0 or 1,) and vice versa. Rotate bits, addressed by the bit.

Find most significant set bit of a number - GeeksforGeeks

Given a number, find the greatest number less than the given a number which is the power of two or find the most significant bit number . Examples: The most significant bit corresponds to decimal number 8. A simple solution is to one by one divide n by 2 until it becomes 0 and increment a count while doing this.

Solved: get bits from byte in Python - SourceTrail

To extract bits from a byte, we will use the bitwise AND operator (&) and bit shifting techniques in Python. The bitwise AND operator will help us fetch the targeted bits, while the bitwise right shift operator (>>) will be used to move the bits to the desired position. Here’s the Python function to extract bits from a byte:

python - Lowest/highest bit set in integer. | DaniWeb

Lowest/highest bit set in integer. These two functions compute the orders of the lowest bit and the highest bit set in the binary representation of an integer. I expect them to handle securely very large integer values. def high_bit_order(n): """Return the integer k >= 0 such that 2**k <= n < 2**(k+1).

Bitwise Operators in Python

Python’s bitwise operators let you manipulate those individual bits of data at the most granular level. You can use bitwise operators to implement algorithms such as compression, encryption, and error detection as well as to control physical devices in your Raspberry Pi project or elsewhere.

how to get the thighest bit position in big integers?

>>BITS = [1<<n for n in range (1,1000)] # Use max number of bits here. I have no clue if this is faster or not. The comparison function used. number of bits rather than O (n), so its worth a test. If you run timing test, let us know the results. slow. position. For small r, for example r = (1 << 16) - 1, the result from.

python - Most Significant Byte Calculation - Stack Overflow

For the most significant aligned byte, in Python 3 you can do: return val.to_bytes((val.bit_length() + 7) // 8, 'big')[0] In Py2, you'd have to convert to a hex string and back to match the to_bytes approach. Thanks, that seems like a much better way of doing things, I think i need to do more study on bit operations!

Clearing the most significant bit from an integer - code golf

Removing the most significant bit from an integer N is equivalent to finding the distance from N to the highest integer power of 2 lower than N. Thus, I used the formula N - 2floor (log2N): .² - Logarithm with base 2. ó - Floor to an integer. o - 2 raised to the power of the result above. - - Difference. b¦C also works... doesn't it?
