Find most significant bit of a BigInteger. Ask Question. up vote 1 down vote favorite. 1. I have read many fine algorithms for identifying the most significant bit for 32 and 64bit integers (including other posts here on SO). But I am using BigIntegers, and will be dealing with numbers up to 4000 bits long. (The BigInteger will hold the Get the most significant bit from an 8bit value. Ask Question.
up vote 1 down vote favorite. I know there are similar questions on this site, however, I couldn't seem to find something that really helped me out with the issue i'm having. So far: I have 1byte (8bits) that could be any combination of 1's and 0's. The bit b7 is the sign bit (the most significant bit), and b0 is the least significant. I'll start with the most basic bit hacks and gradually progress to more difficult ones. I'll use examples to explain how each bithack works.
Logic to check Most Significant Bit (MSB) of a number We use bitwise AND& operator to check status of any bit. Bitwise AND operation evaluate each bit of resultant value as 1, if corresponding bit of operands is 1.
