What we will cover Why do we need floating point representation? Format of Floating Point Representation. Limitations of traditional float point representation. So, if we have fixed point representation why do we need floating point representation? And answer to our question is very simple, we humans are very greedy! "We want more in least efforts!" Means we want to store more number in less space. And we will give the answers of all your questions. Why do we need floating point representation? It provides larger range of numbers with limited number of bits. Comparison from traditional floating point representation Let's assume that we have a register of 8 B so the range of the number that we can store in two's complement will be -2^7 to 2^7-1. Means from -128 to 127. Remember this above range and you will see at the end of this topic, how IEEE 754 is better in storing. Format of Floating Point Representation There are three terms in the representation which I will ex...
