$\%$ Main function that handles user input and calls the respective functions

$\%$ to compute the IEEE $75432-$bit floating point representation.

$\%$ Step $1$: Get the floating$-$point number from the user.

num $=$ input$(\text{'}$Enter a floating$-$point number: $\text{'})$;

$\%$ Step $2$: Get the sign bit $(0$ if positive, $1$ if negative$).$

$\%$ Call the get$\_$sign$\_$bit function to determine the sign of the number.

sign$\_$bit $=$ get$\_$sign$\_$bit$($num$)$;

$\%$ Step $3$: Convert the number into scientific notation $($mantissa and exponent$).$

$\%$ Call the get$\_$scientific$\_$notation function to get the mantissa and exponent.

$[$mantissa$,$ exponent$]=$ get$\_$scientific$\_$notation$($num$)$;

$\%$ Step $4$: Adjust the exponent for IEEE $754$ bias $(127$ for $32-$bit$).$

$\%$ Call the get$\_$exponent$\_$bits function to convert the exponent into an $8-$bit

$\%$ binary string after applying the bias.
