#'
#' @title returns the minimum and maximum of a numeric vector
#' @description this function is similar to R function \code{range} but instead to not return
#' the real minimum and maximum, the computed values are multiplied by a very small random number.
#' @param xvect a numerical
#' @return a numeric vector which contains the minimum and the maximum
