DESCRIPTION
     _E_c_v_t converts the _v_a_l_u_e to a null-terminated string of  _n_d_i_-
     _g_i_t  ASCII  digits and returns a pointer thereto.  The posi-
     tion of the decimal point relative to the beginning  of  the
     string is stored indirectly through _d_e_c_p_t (negative means to
     the left of the returned digits).  If the sign of the result
     is negative, the word pointed to by _s_i_g_n is non-zero, other-
     wise it is zero.  The low-order digit is rounded.

     _F_c_v_t is identical to _e_c_v_t, except that the correct digit has
     been  rounded for Fortran F-format output (fw.d), where _d is
     equal to _n_d_i_g_i_t_s.

     _G_c_v_t converts the _v_a_l_u_e to a null-terminated ASCII string in
     _b_u_f  and  returns  a pointer to _b_u_f.  It attempts to produce
     _n_d_i_g_i_t significant digits in Fortran F format  if  possible,
     otherwise  E format, ready for printing.  Trailing zeros may
     be suppressed.

BUGS
     The return values point to  static  data  whose  content  is
     overwritten by each call.
