        !            25: ASCII digits
        !            26: and returns a pointer thereto.
        !            27: The position of the decimal point relative to the

        !            40: .I Fcvt
        !            41: is similar to

        !            47: then the returned string is null.
        !            48: Otherwise,
        !            49: .IR decpt + ndigit +1
        !            50: characters (including terminating null) are returned.

        !            52: .I Gcvt
        !            53: converts the

        !            55: to a null-terminated ASCII string in

        !            61: significant digits in Fortran F format if
