Range is the range of numbers that can be represented by the system. Obviously the
largest would be the positive number with the largest mantissa (all 1s) and the largest
exponent (all 1s). The actual value of this number would be 1.(1 - 220) * 2128.
The smallest number would have the same magnitude in the mantissa, but would be
Maximum and minimum exponent depend on the bias used for the exponent. Given 8
bits for the exponent, the bias would be 127. Thus we can represent exponents from –127
