Notes

---

      Notes: Why is this routine needed? Try the following:
        print,string(230d0-5e-14,format='(I3)')
        Try it again without the format. The I format does
        not round, but the F format does. This routine
        uses that fact and makes it convenient to do.
        The result has no spaces on the ends so varying length
        values will not line up (except integers).
