We are required to calculate the value of 0.75 minus -65.25, which is equivalent to adding 0.75 and 65.25, and then representing the result using the IEEE 754 single-precision floating-point format.Firstly, we need to convert both 0.75 and 65.25 into their respective IEEE 754 single-...

The IEEE double format has a significand precision of 53 bits and occupies 64 bits overall. Two classes of extended floating-point formats: single extended and double extended. The standard does not prescribe the exact precision and size of these formats, but it does specify the minimum ...
The IEEE double-precision (64 bit word) floating-point format The actual value v represented by the contents of the word is obtained by the following rules, denoting 0 (bold) =0000 and 1 (bold) =1111: a. If S=0 or 1 and E=(11 1111)2=(2047)10 and F≠0 then v=NaN (not-a-...
