$)$ The floating point number format for a machine has the word in two parts: a $10-$bit mantissa and a $6-$bit exponent. The

mantissa is in $2$s complement form and the leftmost bit is the sign bit. The binary point is to the right of this sign bit. The

exponent is in excess $32$ notation. What is the decimal equivalent of the floating$-$point number in the below

representation?
