#' @format 
#' A list containing:
#' \itemize{

#'   \item \code{float.base} radix
#'   \item \code{float.digits} the number of bits for the sign+significand
#'   \item \code{float.exponent} number of bits for the exponent
#'   \item \code{float.min.exp} "largest negative" (smallest) integer for the
#'       exponent that generates a normalized floating-point number
#'   \item \code{float.max.exp} largest integer for the
