IEEE floating point

Question

in IEEE floating point representation, all the exponent bits are one and mantissa bits are non zero. this represent

A) 0

B) infinity

C) denormalized value

D) error

Comments

it denote NAN(not a number), so option D) is correct..

if exponent is all 1's and mantissa=0, then it denotes infinity

Answer 1

Here E= exponent and M= mantissa

So as per your question E= all 1 and M$\neq$0 represent error

For zero E=0 M=0

E= all 1 and M=0 infinity
