Web1 Answer. The number of bits required to represent an integer n is ⌊ log 2 n ⌋ + 1, so 55 2002 will require ⌊ 2002 log 2 55 ⌋ + 1 bits, which is 11, 575 bits. Added: For example, the 4 -bit integers are 8 through 15, whose logs base 2 are all in the interval [ 3, 4). We have ⌊ log 2 n ⌋ = k if and only if k ≤ log 2 n < k + 1 if ...

WebInteger Now, 16 bits make an integer. The first start byte means LSB (least significant byte) and the last byte means MSB (most significant byte). The value for 2 16 will be 65536. That means 65536 numbers of combinations or values will be possible in an integer. An integer is also called as a word. But, a word cannot be signed. Webint: At least 16 bits, and at least as wide as short. long: At least 32 bits, and at least as wide as int. long long: At least 64 bits, and at least as wide as long. Signedness Unqualified char may be signed or unsigned, which is implementation-defined. Unqualified short, int, long, and long long are signed.

WebWe have also seen previously that an 8-bit binary number (a byte) can have a value ranging from 0 (00000000 2) to 255 (11111111 2 ), that is 2 8 = 256 different combinations of bits forming a single 8-bit byte. So for example an unsigned binary number such as: 01001101 2 = 64 + 8 + 4 + 1 = 77 10 in decimal.
