Consider a 10 bit floating point number system. The sign bit is the most significant bit. 4 bits are reserved for the exponent and remaining 5 bits are the mantissa. A bias of 7 is to be used. What is the floating point representation of number 228. b- Consider a 10 bit floating point number system. The sign bit is the most significant bit. 4 bits are reserved for the exponent and remaining 5 bits are the mantissa. A bias of 7 is to be used. What is the floating point representation of number 28.75 c- Using the rules for floating point addition, add the two floating point numbers in (a) and (b) and present the result as a binary floating point number. Please note that it is not allowed to add the numbers in decimal number system and represent the number in floating point
