AERR meaning in Computing ?

Answer: What is Absolute Error mean?

The approximation error in some data is the discrepancy between an exact value and some approximation to it. An approximation error can occur because:

the measurement of the data is not precise due to the instruments. (e.g., the accurate reading of a piece of paper is 4.5 cm but since the ruler does not use decimals, you round it to 5 cm.) orapproximations

In the mathematical field of numerical analysis, the numerical stability of an algorithm indicates how the error is propagated by the algorithm.
