WebJun 10, 2014 · From your description, you said you had a 24-bit binary string that represented a 2's complement formatted integer value. To convert that into an equivalent 32-bit binary string one only has to extend the left-most bit (i.e., the "sign" bit) all the way to fill out the 32-bit string. Two's complement is a mathematical operation to reversibly convert a positive binary number into a negative binary number with equivalent (but negative) value, using the binary digit with the greatest place value to indicate whether the binary number is positive or negative (the sign). It is used in computer science as the most common method of representing signed (positive, negative, and zero) integers on computers, and more generally, fixed point binary values. When the most sig…
