Q4.5 8 Points Calculate how the base 10 number 12.5 is represented as a 24-bit floating-point number on a computer using the following floating-point representation. The first bit is the sign bit, the next 7 bits are the exponent (represented in 63 bias notation) and the remaining 16 bits represent the mantissa (with the usual normalisation for binary floating-point representations). (First, transfer this into fixed point binary format, and then transfer this into a floating-point number.)
