I'm doing analysis on binary data. Suppose I have two uint8 data values: a = uint8(0xAB); b = uint8(0xCD); I want to take the lower two bits from a, and whole content from b, to make a 10 bit value. In C-style, it should be like: (a[2:1] << 8) |...

Edit: Problem solved, advert your eyes from the below code though, haha, I had some things conceptually wrong from the beginning. I've been trying for longer than I care to admit to count the non-zero bits in a wide variety of 32-bit integers, but always seem a bit off. So...

I'm trying to create a double by appending the binary representations of two ints. This is what I have now: int i = arc4random(); *(&i+1) = arc4random(); double d = *(double*)&i; I hoped the double pointer would also use the value in the &i+1 address, and this is indeed the...

In ObjC, a bool's bit pattern could be retrieved by casting it to a UInt8. e.g. true => 0x01 false => 0x00 This bit pattern could then be used in further bit manipulation operations. Now I want to do the same in Swift. What I got working so far is...

As per the C standard the value representation of a integer type is implementation defined. So 5 might not be represented as 00000000000000000000000000000101 or -1 as 11111111111111111111111111111111 as we usually assume in a 32-bit 2's complement. So even though the operators ~, << and >> are well defined, the bit...

Looking at x86 assembly produced by a compiler, I noticed that (unsigned) integer divisions are sometimes implemented as integer multiplications.

Here is a C++ class for revering bits from LeetCode discuss. https://leetcode.com/discuss/29324/c-solution-9ms-without-loop-without-calculation For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000). Is there anyone can explain it? Thank you so very much!! class Solution { public: uint32_t reverseBits(uint32_t n) { struct bs...

This question already has an answer here: What are bitwise shift (bit-shift) operators and how do they work? 5 answers given int a = 1; (00000000000000000000000000000001), what I did is just a=(a<<31)>>31; I assume a should still be 1 after this statement (nothing changed I think). However, it turns...

The method convertToBinary is used to show the 8bit binary number, public static String convertToBinary(int a){ String binary=""; for(int i=0;i<8;++i){ Integer bit=new Integer(a&1); binary=bit.toString()+binary; a>>=1; } return binary; } public static void main(String[] args) { int a=-9; System.out.println(convertBinary(a)); //11110111 System.out.println(convertBinary(0xaaaa)); //10101010 System.out.println(convertBinary(a&0xaaaa)); //10100010 System.out.println(convertBinary((a&0xaaaa)>>1));//01010001 } The last...

I wanted to try to get only the four bits from the right in a byte by using only bit shift operations but it sometimes worked and sometimes not, but I don't understand why. Here's an example: unsigned char b = foo; //say foo is 1000 1010 unsigned char temp=0u;...

Here is the code: int i = 200; byte b = (byte) 200; System.out.println(b); System.out.println((short) (b)); System.out.println((b & 0xff)); System.out.println((short) (b & 0xff)); Here is the output: -56 -56 200 200 Bitwise AND with 0xff shouldn't have changed anything in b, but apparently it does have an effect, why?...

Can anyone give a hint how to approach this problem? Given an array A. Is there any subset of array A in which if we do AND of all elements of that subset then output should be in power of two. I've thought of generating a power-set and solving but...

The question is : x and y are two floating point numbers in 32-bit IEEE floating-point format (8-bit exponent with bias 127) whose binary representation is as follows: x: 1 10000001 00010100000000000000000 y: 0 10000010 00100001000000000000000 Compute their product z = x y and give the result in binary IEEE...
