Consider a 12-bit floating representation that uses the leftmost bit for the sign, the next 4 bits for the exponent with a bias of 7 , and the rightmost 7 bits for the normalized mantissa. Part 1 (12 Points): Give the decimal equivalent of the following 12-bit floating point numbers in hexadecimal: 0xAC8 Part 2 (12 Points): Convert the decimal number 0.28125 to 12 -bit floating point representation in hexadecimal
