    * Converts $n from Arabic digits to Roman digits.
    * This is accurate from 1 to 4999 and only for integers, since the
    * extensions to write the numbers greater than 4999 and the fractions are
    * not implemented.
    * Note that there is no way to write negative number ans zero, as they were
    * not used by Roman. Plus, numbers are truncated to integers, so that 4.2
    * will be converted to IV.
