Answer

Normalization: in the Context of computer performance analysis, Normalization is the process of expressing a statistical performance measure as a ratio to the performance of a system to which on comparisons is made . In the context of floating point representations normalizing a number means adjusting the exponent so that the left most bit of the significant will be 1.

Example : x=10110.101 the given fractional value has to normalize in the following format.{X=1.b1b2b3…..X2m=1.fx2m (where “f “is a fractional part, “m” is the exponent and b is either 0 or 1   ) }

The normalized form of X is :- X= 1.0110101x24
