floating point representation conversion - machine epsilon etc

Floating-point representation Consider a computer that stores information using 9 bits words. The first bit is for the sign of the number, the next 4 for the sign and magnitude of the exponent and the last 4 for the magnitude of the mantissa. The mantissa is normalized as described in class and in the textbook. a. Convert 100011010 to a base-10 system b. What is the highest number that can be stored on this computer? c. What is the lowest positive number that can be stored on this computer? d. Determine the machine epsilon
