Is every binary number start with 0?

Question

Is it true that every binary number start with 1 ?
if it is true then why 1 is starting of any binary number

Answer 1

It depends on how you perceive the binary number. If it's 8-bit, then it will be left-padded with 0 until the number length is 8.

For example, ✌ = 0000 0010.

The same goes for 16-bit, 32-bit & etc. and that's how we interpret it. If you really want to ignore the leading 0, then you may assume the non-zero number comes along with the carry. 😉
