For each id(row i.e exponent and mantissa) there is a corresponding red statement you hv to tell that it is true or false.
All 0 exponent and non-zero mantissa means a number is denormalized in IEEE 754 - no implied 1 before ".". Also, bias for denormalized numbers is "-126" and that for normalized is "-127".
Similarly, we can see for negative numbers.
sir please correct the sign of power in the below parts.minus signs are missing.
(2−2-23 )×2127 Largest normalized number
(1−2-23)×2−126 Largest de-normalized number
Also please explain why there is a difference in the highlighted red part. For largest denormalized I understood its a geometric series of mantissa part but I didn't get why there is change in largest normalized part even if mantissa are same.
