Questions tagged [bit]

A bit is a single binary digit.

A bit refers to a single binary digit, the smallest possible amount of information. In print is usually represented as either 0 or 1, with many different representations in technology, like the presence or absence of an electric current or magnetic field.

Eight bits form a single , although historically the term has been used for other sizes as well.

JavaScript bitwise NOT ~ doesn't produce same result

I am attempting to invert the binary digits of a base-10 value using JavaScript, according to this W3Schools page, JavaScript's Bitwise NOT operator (i.e. ~) should do just that. In an example they show ~5 resulting in a value of 10, but when I…

Sign extending to 32 bits, starting with n bits - C

I am new to C and getting some practice with bit manipulation. Suppose I have an n bit two's complement number such that n > 0 and n < 31. If I know the size of n in advance, how can I sign extend it to 32 bits? If n was 16 bits, int32_t…

What happens to the bits of a float during division?

I have a homework assignment which requires me to divide a 32-bit single precision floating point integer by 2 in C using bitwise operations (if statements and for loops can also be used). The float's bits are represented as unsigned integers so we…

Manually changing a group of bytes in an unsigned int

I'm working with C and I'm trying to figure out how to change a set of bits in a 32-bit unsigned integer. For example, if I have int a = 17212403u; In binary, that becomes 1000001101010001111110011. Now, supposing I labeled these bits, which are…

Issue clearing bits in 128 bit integer array

My goal with this program is that I want to be able to set 1000 bits to 0 or 1 separately, for this I'm using an array of 128 bit integers. Now the issue is when I simply clear_bit(3), bit 35 is also being cleared (and vice versa). 3 & 35 are…

How to compute hamming code for 10 bits?

I have seen examples of hamming code detection and correction with 8 bits or 12 bits. Suppose I had the bit string: 1101 0110 11 which contains 10 bits. Do I need to add two additional bits to that bit string to complete the nibble? If so do I add…
