binary representation
Real numbers, not just integers, can also be written in binary notation, by using binary digits after a ‘binary' point, just as familiar decimal representations of real numbers are written to base 10. For example, the number 
, which equals 0.1 in decimal notation, has, in binary notation, a recurring representation: 0.00011001100110011…2.
