Q. What do you mean by Exponent?

The exponent field needs to represent both negative and positive exponents. To perform this, a bias is added to the actual exponent in order to get the stored exponent. For the IEEE single-precision floats, this value is 127. Therefore, an exponent of zero means that 127 are stored in the exponent field. A stored value of (73.Exponents of -127) or (all 0s 200 indicates an exponent of (200-127) and +128 (all 1s) are reserved for special numbers.

Special Cases:

To represent zero- All the bits are zeros.

To represent infinity-All exponent bits are 1s and magnitudes are 0s.

For double precision, the exponent field is 11 bits, and has a bias of 1023.
