Additionally, we make experiments with double and single precision to calculate the errors that can introduce the single precision, and even when its use reduces the computing time from 30% to 50%, it is necessary to evaluate the effect of the introduced error by using only seven significant digits in the floating numbers and investigate if this error affects considerably the result of the modeling.
