Floating-point representation:

In this representation, numbers are represented by a mantissa comprising the significant digits and an exponent part of Radix R.    The format is:
                                                      

Numbers are often normalized, such that the decimal point is placed to the right of the  first non zero digit.

For example, the decimal number,
                               5236     is   equivqlent to   

To store this number in floating point representation, we store 5236 in mantissa part and 4 in exponent part.
