How many bits are need to represent some entity given its range of numbers?

Question

Hi I need some help on converting the range to a number of bits. How would I calculate that? From what I know a range of 6 should convert to 64 I believe. So how would a range of 365 for example, calculate into bits?

Answer 1

How many times can it be divided by 2 until the quotient is 1. That is the number of bits required to represent that number.

Answer 2

This is an iterative process and, it's so involved that you will usually find tables of ranges for careers needing that information. To do it yourself, here is a how-to page:
