Question $2.$

a$.$ Convert the decimal number $-0\mathrm{.}00000007830465805{10}^{-15}$ to the format SEEMMMMMM with the exponent stored excess$-25.$ The implied decimal point is at the start of the mantissa. Use the standard $0$ for positive numbers and $1$ for negative. Note carefully the number of digits in the mantissa.

b$.$ What is the smallest number $($i$.$e$.$ closest to zero$)$ you can use with this format before underflow occurs? There should be a positive and a negative version of this smallest number.

c$.$ What is the largest number $($i$.$e$.$ furthest away from zero$)$ you can use with this format before overflow occurs? There should be a positive and a negative version of this largest number.
