# Extra Credit 3, Double Precision (10 points)

Modify the **full** program resulting from Homework 14 so that **all** real variables support at
least 12 decimal digits of precision. Use the selected_real_kind function. Set the
convergence criteria (eps) for your iteration loop to 1.e-10.** **

**
**

### Grading will be as follows:

**Proper use of selected_real_kind - 3 points**
Proper setting and use of the convergence criterion - 2 points

**
Degree of thoroughness in setting the correct KIND for real variables - 5 points**
