Firstly I explain you What is Floating Point Number,as we know that number has two parts i.e. part before decimal and part after decimal.The part before decimal is an integer part and part after decimal is a fractional part.

Point to Remember:-In floating point representation the second register is used to store that number which specify decimal of that number.

Let us take an example,the number 345.55 can also be written as 3.4555 * 10^2.So from this example we conclude that a no. is a combination of Mantissa(or fraction) and exponent.

Representation of a number(Examples):-

1)64*10^3

0    1    0    0    0    0    0    0        =Mantissa

0    0    0    0    0    0    1    1         =Exponent

2)-64*10^3

1    1    0    0    0    0    0    0         =Mantissa

0    0    0    0    0    0    1    1         =Exponent

3)64*10^-3

0    1    0    0    0    0    0    0         =Mantissa

1     1    1     1     1     1    0    1          =Exponent
