In this video, the difference between the Fixed Point and Floating Point Representation is explained. And how very large or very small numbers are stored in a computer using the floating point representation is explained. Also at the end, how to represent any Binary number in Floating Point representation is explained through examples.

Fixed Point Representation:
In Fixed Point Representation, the position of the radix point remains fixed. Because of the fixed radix point/ decimal point, for a given number of bits, the range of Binary numbers gets restricted.
Using 16 bits or 32 bits, in a fixed point representation, it is not possible to represent very large or very small numbers.

Floating Point Representation:
In Floating Point Representation, the position of the radix point / Binary Point is dynamic. Therefore, it is possible to represent very large or very small numbers.
The floating Point Number representation is similar to the scientific notation used for the decimal numbers. It is a normalized representation.
In Floating Point Representation, there is only a significant digit before the Binary point.
The floating Point Representation consists of 3 parts.
1) Sign
2) Significand
3) Exponent

In this video, how to represent any Binary Number in a floating point representation is explained using the examples.
