Binary

2^...   Back

 

Binary (or base-2) is a representation of numbers using only 2 symbols: ones and zeros.


2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0
128 64 32 16 8 4 2 1

Using the above table, you can represent any number in Binary. For example 201:


128 64 32 16 8 4 2 1
1 1 0 0 1 0 0 1

128 + 64 + 8 + 1 = 201
