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 ...

WebAug 9, 2024 · In fact you need 7 bits to write 64. Notice that this is the answer you get if you write ≤ for 2 n − 1 but < for 2 n. Another way to describe the rule with fewer symbols and more words is that you need exactly n binary bits to write x if x is less than 2 n but not less than 2 n − 1.
