A machine stores floating point number in a $9-$bit binary word. The first bit is for the sign of the number, the second bit is for the sign of the exponent, the next $3$ bits are for the magnitude of exponent, and the final $4$ bits are for the magnitude of mantissa. The base$-10$ number that $(010100011{)}_2$ represents in the above given $9-$bit format is
