A real number is a number that contains a decimal point. You can not place a decimal point inbetween 1′s and 0′s, so instead we use floating point representation. In Floating Point Representation real numbers are stored as two separate bits of data. *Mantissa* is the name of the location where the complete number without the decimal point is stored. *Exponent* is the name of the location where the number of places that the decimal point must be moved is stored. The point has to be moved to the very beginning of the number. The base in binary is always 2. .
