In hemat: Hematimetric Indices Calculator

#' Calculate Mean Corpuscular Volume (MCV)
#'
#' MCV measures the average volume of red blood cells in a blood sample.
#' @param ht Numeric value representing the hematocrit in percentage.
#' @param rb Numeric value representing the red blood cell count (millions/ µL).
#' @returns Numeric value representing the MCV in femtoliters (fL).
#' @examples
#' calc_mcv(40, 5)
