Question

general purpose of numerical error?​

Answer 1

Answer:

In software engineering and mathematics, numerical error is the error in the numerical computations.

Time series of the Tent map for the parameter m=2.0 which shows numerical error: "the plot of time series (plot of x variable with respect to number of iterations) stops fluctuating and no values are observed after n=50". Parameter m= 2.0, initial point is random.

Answer 2

Error — that is, how far an answer is from the true value — can be measured in two different ways: as an absolute value, or as a relative value. Absolute error is the difference between the computed (or estimated) answer and the true answer. Relative error is the absolute error divided by the true answer.
