Explanation / Answer

//C++ code
#include <iostream>
#include <cstdlib>
#include <string>
#include <math.h>
using namespace std;

int main()
{

unsigned int sign, exponent, mantissa;

cout << "Enter sign bit: ";
cin >> sign;

cout << "Enter exponent: ";
cin >> exponent;

cout << "Enter mantissa: ";
cin >> mantissa;

float result = 1.0;

// using the sign bit
if(sign == 1)
{
   result = result* pow(-1, sign);
}

result = result * int(mantissa) * pow(10,int(exponent));

cout << "result: " << result << endl;

return 0;
}


/*
output:

Enter sign bit: 1
Enter exponent: -3
Enter mantissa: 4
result: -0.004

*/
