Hi. This code needs to be changed. It is not working. the file to be changed is MyFloat.cpp. It is called from main.cpp, which i have provided as well. Can you implement functions in a way that when called from main, output whats given in the prompt? (prompt (very bottom) and code are given below) ! This is inline assembly intel x86. (Please do correctly and quickly, Will def leave thumbs up!). Thank you!

PROMPT is down below all the way at the bottom.

MAIN. CPP :

#include  #include  #include "MyFloat.h" using namespace std; int main(int argc, char** argv){ float f1, f2; //float fres;  MyFloat mfres; cout.precision(1000); if(argc != 4){ cout"Usage: " " float_a +/- float_b" else{ f1 = strtof(argv[1],NULL); f2 = strtof(argv[3],NULL); MyFloat mf1(f1); MyFloat mf2(f2); cout ' '' ' if(argv[2][0] == '+'){ //addition  //fres = f1 + f2;  mfres = mf1.operator+(mf2); //cout  cout "My Add: " else if(argv[2][0] == '-'){ //subtraction  //fres = f1 - f2;  mfres = mf1 - mf2; //cout  cout "My Subtraction: " else{ cout "Only + and - are supported but received operator: " //cout  } return 0; } MYFLOAT.CPP:

PROMPT:

clean:

Print all real numbers to two decimal places unless otherwise stated .The examples provided in the prompts do not represent all possible input you can receive. All inputs in the examples in the prompt are underlined You don't have to make anything underlined it is just there to help you differentiate between what you are supposed to print and what is being given to your program .If you have questions please post them on Piazza For this assignment you will be implementing floating point add and subtract without using the hardware's floating point or double precision add. This will give you a better understanding of how difficult they are to work with and a higher appreciation of the hardware for doing this for you. You will be turning in a file called MyFloat.cpp and its associated header file, MyFloat.h, that implements your own floating point number. This object should support both + and -. 1. You may not use floating point or double precision add in your solution. This means that 1. you should not have the following in your program 1. float x,y; 2. MyFloat should represent a float using three unsigned integers: sign, exponent, and mantissa. MyFloat must have the following private methods defined on it. These functions must be implemented using inline assembly. 1. void unpackFloat(float f); 3. 1. Given a float f this function should set sign, exponent, and mantissa to the appropriate values based on the value of f. 2. float packFloat) const; 3. MyFloat must have the following public functions defined on it 1. This function should return the floating point representation of MyFloat You may declare and initialize variables to a constant in C as well as return a value but you should do no other calculations. 4. MyFloat operator+(const MyFloat& rhs) const; 1. 1. This function should add this to rhs and return the result of the addition When adding the two numbers, the maximum amount of precision must be maintained 2. Before doing the addition you should restore the leading 1. This means that the mantissa will end up taking 24 bits. Since you are adding two 24 bit numbers together the result could take up to 25 bits Be careful when shifting. Since the numbers are 32 bits, the maximum amount 1. 2. 3.
