1. If the correct answer is 100 and it is stored as 100.9, that is not too far off. However, 1.9 is a long way from an answer of 1.0. The latter presents a greater error.
2. If we denote the correct answer as 'x' and the stored value as 'x0', then the absolute error is simply ______________
3. In the following example, what is the absolute error in both cases?
4. It is critical to see what the error is in relation to _______________________
5. The actual number difference beween the desired value and the rounded value is called the ___________________________
6. The percentage difference between the desired value and the rounded value is called the ___________________
7. In the following example, fill in the blanks for 1. and 2.
8. For example, if p = 0.4 and p? = 0.404, the absolute error in the approximation is:
9. If p = 0.4 and p? = 0.404, the relative error in the approximation is:
10. Using 8 bit fixed point unsigned fraction with 4 bits for the decimal points: Is the calculation shown to find the absolute error trying to represent 8.8 correct? (True or False?)
11. Errors, especially rounding errors, can have deadly consequences. e.g. the 1991 patriot missile misses scud and 1996 - Ariane rocket explodes!
12. An absolute error could also be be described as the approximate value - true value.
13. The relative error is the absolute error/absolute error +1 1 * 100
14. Some people tend to use the term accuracy when speaking of absolute errors and the term precision when speaking of relative errors
15. What is the absolute error? Refer to the image below.
