Consider two 32-bit floating-point numbers (X and Y) with a sign in bit position 31, a two's complement unbiased 8-bit exponent in positions 30-23 and a two's complement 23-bit mantissa in bits 0 through 22. The mantissa is a fraction less than one and there is no implied 1-bit in the normalized form The bit strings representing the 2 numbers are given in hexadecimal notation for convenience: X- 00C0 0000 Y 813F FFFF a. Calculate XY b. Calculate X *Y
