Relpy the following two questions and complete the corresponding two computations.
Why do we require signed-and-magnitude representations of binary numbers in computers?
Computation 1: Represent decimal values: -37, -54, and 56 in binary by using signed-and magnitude representation.
Why do we require floating-point numbers in computers?
Computation 2: Represent decimal values: -23.2, 9.32, and -32.5 in binary for IEEE standard 32-bit floating-point value.
