My Doubt is:-

E is of 11 bits, we know that if all 11 bits are used then it represents a special number likewise if all are 0

so Emin = 00000000001 , Emax = 11111111110 so 1<=E<=2046.

My doubt is why we are using all 1's, when we are given a number we define the exponent bit by adding the bias term into it for which here it will be 1023 right ?

I am confused when we use bias term and when we use all 1's like here we did. Please clarify little about it
