In the previous blog posts, we answered

- Question 1 of 5 “What is machine epsilon?” and
- Question 2 of 5 “How do I find machine epsilon using MATLAB code?”

Here we answer the next question.

**Future posts will answer these questions**

Question 4 of 5: What is the significance of machine epsilon for a student in an introductory course in numerical methods?

Question 5 of 5: What is the proof that the absolute relative true error in representing a number on a machine is always less than the machine epsilon?
